If you're really going to a lot of developer events, and rinsing your network to its fullest extent then I'd suggest keep trying. Assuming you're talking about hiring developers for market rate, then you should have success eventually.

You could try to ask friends as to whether anything in your proposition is putting off potential hires.

Finally, personally I wouldn't bother with Craigslist, but you could try the job/career functionality on both Github and Stackoverflow.com.

Hope that helps
