15 high-paying jobs you can do on the side

Trying to make some extra cash? Have free time you don't know what to do with? Trying to develop or hone a new skill? You should consider getting a side gig.

FlexJobs, an online service specializing in telecommuting and remote work, recently put together a list of 15 high-paying jobs 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, the director of online content for FlexJobs, says "side jobs" are defined as anything part-time, including freelance, temporary, short- or long-term, work-from-home, or in-person flexible gigs.
