13 high-paying side jobs for people in their 20s

You recently graduated and got your first "real" job - congrats! That probably means that you'll be moving into a new apartment, where you'll have rent to cover, bills to pay, and furniture to buy. Oh, you'll also need a new work wardrobe - and you'll probably want to grab the occasional drink or meal at your new neighborhood hot spots.

All of those things cost money - a lot of it. And chances are, that job you just accepted doesn't pay as much as you'd like.

Luckily, there are some easy ways to make extra cash when you're in your 20s and trying to make ends meet.

FlexJobs, an online service specializing in telecommuting and remote work, recently put together a list of high-paying jobs that you can do on the side.

To qualify for the list, each job had to be considered "flexible" - and not full-time - and had to pay at least double the federal minimum wage of $7.25 an hour, according to the job posting on FlexJobs.

Brie Reynolds, director of online content for FlexJobs, says that "side jobs" are defined as anything part-time, including freelance, temporary, short- or long-term, work-from-home, or in-person-flexible gigs.
