Looking to build portfolio, will freelance for food stamps

I'm looking to build a portfolio of projects, and I'm willing to work for really cheap to do it. Unfortunately, the HN freelancer thread doesn't really seem to have many people looking for freelancers, and Elance/Freelancer.com have way too many low bidders from developing nations so I haven't had much success there either.

Skills: Ruby/Rails, Java (&J2EE), C, C++, some PHP & Python

Contact me if interested at username at gmail. Thanks!
