Yeah Freelancing seems like the best option if you're not planning on doing it for long.
Maybe something more "local" like Malt (malt.fr) for the French around here would be easier to get going in a short time. Less competitions and more direct offers.
I personally have no experience using freelance services - in my case I was an IT help desk intern for almost 2 years and built small list of people who would come to me outside of work for IT help. They still do, though these days I'm a little to busy with my actual job to assist as much.
