If you’re short a little cash at the end of the month, here are ten ways to make a quick buck. While these may help you make ends meet during an emergency or cover a one-time expense, be sure to get your spending on track and look for ways to make more money long-term and budget accordingly.

1. Sell your blood or plasma

Selling blood is an easy source of money, provided you meet the requirements. There are hundreds of for-profit blood centers out there that will pay up to $50 for your blood or plasma. Check out Biolife Plasma to see if there are donation clinics near you. If you’re feeling really hard-core (or in dire need of cash) you can also sell your sperm (men), eggs (women), white blood cells and even hair. Keep in mind that the Red Cross recommends you wait 56 days between blood donations and 28 days between plasma donations.
Here are a few donation clinics in major cities:

2. Cut down your costs

There are any number of money leaks you can plug to earn some fast cash: get rid of cable, use cash back websites and rewards malls to lower the cost of spending, and hunt for coupons on everyday purchases. Then, use that money for whatever you need.

3. Sell your junk

You most likely have a bunch of used or even unused things lying around you no longer need or want. Get them online using Craigslist, eBay, or any other community bulletin board, or go old school and have a garage sale. Some services will buy your old cell phones, ink cartridges, and the like, so if you find a treasure trove, do a quick Google search of “we buy [whatever it is you want to sell].”

4. Rent it out

Websites like AirBnB make it easy to rent out a spare room in minutes; other websites let you rent out your car, parking spot or even lawn-mowing equipment. However, be sure to check with restrictions on your apartment or rental before signing up.

5. Become a rideshare driver

The taxi industry used to be limited to just licensed, fully employed cab drivers; services like Lyft, Sidecar and RelayRides let anyone with a driver’s license and a clean record earn some money ferrying others around. You can work your own hours, making this ideal for those with a strict day job.

6. Freelance

Whether you’re a handyman, a graphic designer or just an average Joe, websites like TaskRabbit and Fiverr let you sell your skills (or lack of skills). The variety of tasks make it ideal for anyone: You’re likely to find requests for anything from assembling Ikea furniture to user testing.

7. Participate in clinical trials

Like donating blood, another medical fast-cash route is signing up for research testing. Large universities and research institutions need participants for anything from a sleep study to trying out a new drug. Compensation can be under a hundred bucks or up to thousands of dollars.

8. Be part of a focus group

Focus groups are made up of average people used to evaluate and give their opinion on new products or even sit on a mock trial jury. You can earn anywhere from $50 to $300 an hour. Be careful not to lie during the application process, though.

9. Sell to stock photo websites

Websites like iStockphoto and Shutterstock will buy images of everyday images, from an empty teacup to a kid at a blackboard. Thankfully, you don’t have to be the next Ansel Adams to make a sale; routine items are the most in demand.

10. Take paid surveys

Finally, you can get paid to answer surveys through companies like SurveySavvy and Harris Polls. While this can be an easy way to make money online, you’ll have to be careful about scams. Websites like SurveyPolice can help you verify which ones are legit.
