Just stopped at these Internet freelance jobs search and thought it is worth trying. I have not tested the viability of the jobs. But you can always try and get your first Freelance contract from one of them.
Some of these online directories of freelance jobs, will require a paypal account for payment. Not all of them are totally free.
Be aware of Internet scams offering freelance contracts, and asking you to post finished design, all lot of them are about. Or sometimes the services providers have good intentions, but not the advertisers. Do your research beforehand.
