Your best bet is to reach out to your network (friends, former classmates, coworkers, etc.) and let them know you're available. I've also found freelance websites to be pretty hard (I know of some successes, but they were full-time freelancers). If you do a good job, you can escape the race to the bottom. Anecdotally, the best freelance job I got was through Hacker News.
