If you're a good writer but don't have the time to write a lot of extra articles, you can try what I call the "eBay Ad Strategy." There are many high-priced items selling on eBay, such as cars, boats, and motorcycles. Many of these items have terrible descriptions and sales pages. You can contact the owners, tell them that you will write a great sales page for them, and simply ask for 1 percent of the selling price as your fee. They don't pay you anything unless the item sells. This makes the offer appealing to them and because it's a high-priced item, you can easily earn a nice chunk of change from a little bit of work.
Get paid for your opinions. Taking surveys online can be a relatively quick way to earn enough to afford a few extras. Harris Poll Online, for example, awards points for the completion of online surveys, which can take between five and 25 minutes to fill out. Survey takers accumulate points and can redeem them for gift cards from retailers such as Amazon and Starbucks. Other online outfits that will pay you to take surveys include SurveyClub, Global Test Market and Swagbucks. There's no cost to sign up.
If you’ve got some free time and don’t live in the middle of nowhere, becoming a Lyft driver can be a very lucrative side hustle that allows you make money fast. And right now, they’ve got a promotion going on where any new driver will instantly get a $300 bonus after completing their 100th ride. If you start now and hustle hard on the weekends, you can probably unlock that bonus within a few weeks of driving (and that’s in addition to your normal earnings).
