If you have some sort of skill, figure out some way to market it and get some
BTC the good old-fashioned way: With hard work.
Can you write? Check out
http://www.devtome.com/doku.php to earn Devcoins by writing wiki pages, then exchange those on Vircurex for BTC instead.
Can you do anything musical? Set up a Youtube channel or something, don't set up ads, and instead set up a Bitcoin tipping address. Link it in your signature or other places on the forums to attract attention.
Can you program (or, at least, do you think you can program)? There seem to be a ton of "programming" jobs in the Sevices section of the marketplace.
Most of all, my advice is to think outside the box a bit. Clever ideas inherently attract more attention.
