Whatever you do, when first out of college, it can take a long time to build up your experience. It can be a long, frustrating climb, but do have patience and try not to get frustrated when you keep hearing that you need experience to get the job. It really, truly is character-building and most of us (whose dad doesn’t own the company!) have to go through it. Best of luck!
The online application process for these jobs—or perhaps “gigs” is the better word, since they're all for independent contractors—is pretty simple and straightforward with very little required of candidates. Some of these opportunities—like the micro-jobs—you could very well apply and start the same day. And these jobs require very little commitment and can typically be done on your own schedule.
