In 2008, I went to SCALE, which is a Southern Californian Linux/Open Software expo. I met someone from a large company that pays finding fees to people that bring in new talent; he was there hoping to make a couple bucks.

From that, I've got two suggestions. First, go to expos, meet-ups, etc. They sometimes have mini job fairs, or at least people that know about some open positions. Second, find someone that will advocate for you to be hired (greed and friendship are both good motives for that).
