1. Work Overtime and Cash-in Holidays

Work Overtime

Before you try anything else, your first stop for making extra cash should be your existing job. Many employers offer overtime with some regularity to those willing to do it. You may even get a higher per-hour wage for doing so, due to working what are often unsociable hours. This is especially true during the holiday period.

It makes more sense earning extra money doing something you're already familiar with than searching for something else to do in your spare time. Plus, it puts you in the employer's good books, and who knows? It could lead to more opportunities in the future.

A similar option is to cash-in your permitted holiday or vacation time or continue working during paid holidays (Memorial Day, Thanksgiving etc) when you will be paid at a higher rate than those that take the time off.

Exactly how much you will earn obviously depends on your job, but an extra $1,000 is never too far away.

2. Ask For A Raise

Ask For a Raise

Nobody likes asking for more money, but in many positions, it's simply those that asked who are paid the most. There can be a bit of an art to salary and wage negotiations, but the rule of thumb is to focus on the value you have created the company, not on any of the personal reasons for needing more cash.

If you have recently been given more responsibilities or completed a particularly successful project, you have the opportune time to broach the subject of a raise.

Of course, in most cases, there has to be an underlying reason for asking for more money. It's up to you to find this and properly express it to your employer. And, unless you are particularly obnoxious about it, there's no harm in asking.

If your pay is increased, you will gradually see the benefit of an extra $1,000 over time.

3. Sell Your Unwanted Stuff

Sell Your Unwanted Stuff

All of us have at least a few things around the house that we don't use; gathering dust and depreciating in value. You'd be surprised what you can find and what you can sell by doing a thorough inventory of your household items.

Those curtains laying in the attic that you took down last year, that cupboard full of old electronics, the books, and DVDs you're never going to read or watch again - it all soon adds up.

With the rise of local buy/sell pages on social media and traditional online marketplaces like eBay, you're never short of opportunities to offload your unwanted things. And that's without going the old-school route of a yard sale.

Even items you deem worthless like old outdated cell phones can net you a few dollars using online recycling services that will take the details, give you a quote and send you a prepaid box to send it to them in.

4. Flipping and Arbitrage

Flipping and Arbitrage

For those with an eye for a good product, you can take the concept of selling your unwanted stuff and turn it into a weekend business. Flipping or arbitrage, as it's sometimes known, is taking advantage of the pricing discrepancies of products found at yard sales, on buy/sell pages, charity and thrift stores, and on eBay and other online marketplaces.

For example, you might find somebody getting rid of a TV outside their house, who hasn't given too much thought to its value. They just want it gone. You could check online what it's selling for on eBay and bag the profit.

You won't become rich doing this and you have to get some enjoyment out of the process, but if you do it every weekend you can soon begin making consistent cash.

5. Freelance and Sell Your Skills Online

Freelance and Sell Your Skills Online

If you're serious about making an extra $1,000 and have exhausted the usual options like selling your junk or working overtime, it may be time to do some extra work outside of your regular job.

One of the best ways to do this is to sell your skills online, which is otherwise known as freelancing. If you have skills as a writer, graphic designer, you can code or build websites, have experience with certain programs or software suites, know SEO, or wouldn't mind answering the phone and emails for somebody - you can find remote work on the web.

This is typically done via freelance communities like UpWork, and although the pay will start off low due to the global marketplace, you'll soon be able to prove your worth and build a track record.

6. Become a Tutor

Become a Tutor

A more traditional version of selling your skills in your spare time is tutoring. This can vary from teaching somebody to play the guitar to preparing them for their school exams, to helping someone learn English.

There are of course professional tutors for education, but in the free market, there are still plenty of opportunities for those with proven skills and qualifications who want to make a little extra money. As long as you have a high school diploma, you are generally permitted to work with students below this level.

As well as tutoring locally, the internet now also provides another avenue where you can teach people via Skype and other online forms of communication.

If you find you have a knack for tutoring, it's definitely worth pursuing one of the certifications and joining a tutoring association.

7. Drive for Uber or Lyft

Drive for Uber or Lyft

The likes of Uber and Lyft have revolutionized the taxi and private car industry by opening the market up to anybody who can drive. If you have your license and meet a few other requirements, you can become a local driver picking up passengers in your spare time to make some extra cash.

Most money is made in the bigger cities and metropolitan areas, with spikes at evenings and weekends, and early in the mornings when people want to get to work and school.

It's not uncommon for dedicated Uber drivers to make $1,000 in a week, but you can certainly contribute to that pot in your spare time as well.

If you own a van or minibus, you could also set up your own delivery or airport-run business, advertising locally on Facebook. Note that the legalities of this will vary from state to state in terms of licensing.

8. Rent Your Room or Property on Airbnb

Rent Your Room or Property on Airbnb

Online marketplaces like Airbnb have made it easy to rent your room or entire property over the short-term and on your own terms and can be a great way to make some extra cash.

You will do best in and around cities as an alternative to a hotel, or in areas where people tend to go on vacation. However, if you don't mind a longer-term lodger or have an empty apartment or entire property that you can rent out, there will always be somebody who needs a place to stay at a reasonable price, wherever you are located.

Simply register as a host, set your own pricing (based on Airbnb's guidance), and be thorough with the description and photos.

Once you've had a couple of bookings and been well rated by your guests, demand will increase and you can command a higher price.

9. Work for PostMate and Delivery Companies

Work for PostMate and Delivery Companies

In the same vein as Uber and Lyft, there are now a number of delivery companies that are making use of modern app technology and allowing people to easily work their own hours as part-time and full-time delivery drivers.

One of the biggest of these is PostMates. You can walk, drive (your own vehicle), scoot, or even walk, checking-in to see what needs to be picked up and delivered on your patch and getting the job done for up to $25 per hour.

Another “on demand” service of this kind is DoorDash, which focuses on food deliveries for restaurants that don't have their own delivery or takeout service.

While you probably shouldn't give up your career to pursue these types of opportunities, they are definitely becoming a tried and trusted way of making a side income.

10. Rent Your Parking Space

10. Rent Your Parking Space

You can now rent out pretty much anything with the help of the internet and parking spaces are becoming a popular way to earn an extra revenue stream. Obviously, you won't be getting as much as if you were renting out a room, but it's far less intrusive and the income is passive. You don't really have to do anything other than keeping the space empty during the agreed-upon hours.

So, if you live in or around a large town or city and have a driveway or other form of parking space, set up a profile on marketplaces like JustPark. All you have to do is specify the location, size, and available hours, and you can set a price with their guidance.

As long as everything is agreed, you don't need to be there to greet the driver. Furthermore, cancellation is easy if you change your mind, and you don't have to worry about insurance.

11. Handyman Services

10. Handyman Services

Everyone needs a handyman from time to time, and in fact, the number of people with the broad practical skills and inclination to do the job is declining rapidly, leaving the market open to those that don't mind a bit of hard work and getting their hands dirty.

Some of the things you could do might include painting, repairing and building fences and sheds, gardening, garden waste removal, helping people move, home maintenance and improvements, basic carpentry, plumbing and electrical work, electronic repairs (fixing smartphone screens etc), appliance installation, mechanic work, and anything else that takes a bit of skill, time or muscle power.

With social media, promoting handyman services locally couldn't be easier and is a great way to make some extra money in your spare time. You could start with your friends and family and build a client base from there.

12. Pet-Sitting and Dog Walking

10. Pet-Sitting and Dog Walking

If you love animals, one money maker that can be very fulfilling is pet-sitting and dog walking. Pet-sitting is taking care of a pet while the owner is away. This could be a quick daily job when the owner is at work (making sure they are fed and watered, and get a bit of attention), or something longer while the owner is away or on vacation.

Dogs require regular exercise, but their busy or elderly owners sometimes can't take them for walks. This allows dog lovers to charge for the service.

You won't make a quick 1,000 dollars in one day, but depending on how your own work and daily schedule lines-up, this can vary from an evening or weekend gig for friends and family to a full-time business, where you are responsible for dozens of pets.

13. Take Part in Referral and Affiliate Programs

10. Take Part in Referral and Affiliate Programs

Online and offline businesses are always looking for ways to attract new customers. One method of doing this is to use the praises of existing customers and to incentivize them in the process.

This is called a referral or affiliate program, where you get paid for persuading others to buy the product or service.

You can make money doing this casually. For example, if you had an extension built on your house, you may genuinely rate the service high and can take advantage of a referral program by encouraging your friend or family member who is also looking to get some work done.

Others dedicate significant time to earning such commissions and essentially become amateur marketers. This is especially popular on the internet where whole networks exist to connect web-based businesses with individual affiliate marketers who work to promote them online.

So, if you want to earn some extra cash or start a side gig earning $1,000 or more, keep an eye out for affiliate and referral programs for the products or services you buy. Or dive right in with affiliate marketing networks like Commission Junction.

14. Cut the Cable

10. Cut the Cable

Making an extra $1,000 at home is not necessarily just about doing more work, you can also have more savings or disposable income by cutting back on your expenses and making wiser purchasing choices.

One of the easiest ways to do this is to reassess your cable bill, cell phone plan, and other recurring subscriptions.

Firstly, what do you really need? Can you do without movies and sports? Are you using all of that data plan? Once you've settled on what you want, it's now time to shop around for the cheapest provider. For television, it might be that it's cheaper for you to "cut the cable" completely and move over to a couple of streaming services like Netflix and Amazon.

Whatever you decide, you can then contact your current provider and broach the subject of leaving. A lot of times they will offer you a better deal to stay, so be sure to weigh up all of your options before making a final decision.

15. Use Cashback Credit Cards

10. Use Cashback Credit Cards

If you have good credit and the freedom to take out a new credit card, shop around for one that offers cashback or points that can be redeemed for vouchers or other incentives. This is usually applied at a per dollar rate, so it must be a card that you use regularly to be worthwhile.

This won't make you $1,000 on its own very quickly, but when combined with other cost-cutting and money-making measures, it will certainly contribute to the pot. Just make sure you pay the balance off in full for every statement, else the interest might offset any cashback you earn.

16. Don't Ignore Your 401(k)

10. Don't Ignore Your 401(k)

For longer-term financial stability, don't forget your 401(k) retirement plan. In the short-term, you might look at this and think you're wasting money by contributing, but remember that a lot of employers will match your contributions. That's free money in the future.

You can accrue $1,000 fairly quickly, though this obviously cannot be withdrawn until retirement age or if you fall under certain hardship categories.

17. Stop Over-Insuring or Paying Too Much Car Insurance

10. Stop Over-Insuring or Paying Too Much Car Insurance

Data suggests a large percentage of Americans may be over-insuring their vehicles and flushing money down the drain. By over-insuring, we don't mean getting a bad deal (though that should be avoided too).

Over-insuring is when you're forking out for comprehensive plans and collision insurance, when it may be cheaper to replace the vehicle if you're faced with such a scenario.

If you feel your car only has a couple of years left, there's no need to spend hundreds to protect what doesn't necessarily need protecting.

The next thing to consider is your deductible. This is the amount you must pay upfront when an insurance claim is made. The higher deductible you agree, the lower your premium payments.

Then there's the overall plan. Never stick with the same insurer out of convenience. There will always be a better deal out there if you use the price comparison websites and it really doesn't take long to fill out the required forms online.

18. Invest and Save

10. Invest and Save

If you have existing savings, make sure this money is working for you. At the very least your savings should be in a savings account earning interest, not sitting in a basic checking account or worse, under your mattress.

It is also wise to diversify into other relatively risk-free investments. Gold, for example, has consistently beaten inflation and outperformed many savings accounts in returns, over the past 15 years. Gold being a physical commodity is also safe from financial collapses that can wipe out banks and the fiat money in them.

Next on the list is a basic mutual fund managed by a big bank or investment firm. These are riskier than savings accounts, but choosing one with a long track record that doesn't aim for huge returns is usually a safe bet.

Those who don't mind risk for a reward might also consider investing in cryptocurrencies like Bitcoin. As a rule of thumb, when everyone is talking about how high BTC is, stay away. Jump in at the next downturn and ride the wave as more of the general public begin to take part and the value goes back up.

19. Lend Your Money

10. Lend Your Money

One of the best ways to make more money is to lend out your existing money. After all, the only way the bank is making money is by lending out your savings anyway.

It has never been easier to become a lender than with the Peer to Peer (P2P) platforms available online and unlike banks, they don't take a large cut of the interest you earn.

Of course, there are always risks, but you set your own criteria in terms of the types of borrower you accept. You may choose only to lend to Grade A borrowers (those with good credit scores) or mix it up for higher returns.

How much you lend and how much you'll typically get back, is entirely up to you.

20. Donate Blood (Plasma)

10. Donate Blood (Plasma)

Donating blood allows hospitals to save lives when patients have been in horrific accidents or otherwise need transfusions. In the US you can legally donate blood up to twice a week and many charities and organizations will pay you for your time - between $10 and $60. Over a month this can soon add up, especially if you have a rare blood type.

Of course, you will need to be free of blood-based diseases and in good health, but the average person is perfectly acceptable as a blood donor.

Ethically, it's up to you whether you wish to take payment for such an act, but a large percentage of blood banks sell the blood regardless.

21. Donate Your Eggs

10. Donate Your Eggs

Unfortunately, not all women can conceive children with their chosen partner. One solution is IVF treatment, where an egg is taken from the woman's ovaries and fertilized with their partner's or a donor's sperm in a laboratory, before being inserted into the womb to develop.

In other cases, the women's own eggs are not viable and a donor is sought. If you are a healthy woman you could make much more than $1,000 in one day by donating several eggs as part of a donor "cycle."

This should not interfere with your own ability to get pregnant, but you will need to dedicate some time to the procedures. Some clinics will cover travel and expenses on top of any direct payment.

22. Clinical Trials (Drug Trials)

10. Clinical Trials (Drug Trials)

Before a drug can hit the market to treat a disease or condition it needs to be shown to be effective and safe for humans. This also extends to certain cosmetics, foods and other products. At some stage, this means testing them on volunteers and you can be paid quite generously to be one.

While this might sound like a risky prospect, all subjects are closely monitored by professionals for the slightest onset of any adverse reactions and there are rigorous safety and testing procedures that must be completed before any human is involved. The odds of suffering any permanent damage is actually quite low and even then you are insured.

Usually, there are two groups sought for such trials, those with an underlying condition (I.e. the one that is being tested), or generally healthy adults to test safety.

You will be asked to take the time to conduct the trial in a clinical setting and you may be faced with certain dietary restrictions etc.

Depending on the length of the trial, you can make anywhere from a few hundred dollars to a few thousand.

23. Focus Groups

10. Focus Groups

Perhaps a less daunting way of donating yourself to science is via a focus group, which simply aims to collect data about your opinion or response to a product, service, idea, or scientific process.

In marketing, for example, you might be asked to watch a commercial or interact with a product's packaging and then answer a series of questions. The purpose is to gauge the reaction of a small group and extrapolate this out to the rest of their consumer base. In that scenario, you would usually need to meet a desired demographic - I.e. college-educated males, between 25 and 40 years old.

Some of this can now be done online and websites exist where you can provide your personal details and find relevant focus groups to take part in and get paid.

By employing just some of these money-making and money-saving methods, you should be well on your way to quickly making $1,000, and who knows where you'll be if you develop the ideas into fully-fledged businesses?
