I would suggest that you build up a 'professional' social network around you. In Germany http://xing.com is very popular among business people. I do not know enough about other social networks like Facebook or LinkedIn to recommend something to you, but my point is: I do not get my contracts from 'project websites'. Since many years nearly all contracts are the result of recommendations of former clients or people that do what I do. To get your first gig, I would suggest that you ask everybody you know, whether they could use your service, or know somebody who might be interested.

Best luck and have fun.
