My solution has always been.
1) Leverage your network but be specific in the ask "Do you know a programmer that's $20-$40 hour (likely from eastern Europe) that you've worked with and like?"
2) There so many new marketplaces jumping up focused on niches that may be worth trying (ex: http://elto.com & others).

The only other solution (if you want to spend avg. ~$100/hour) is to call a local dev shop and try and get a "bro deal" / that may work great if you live in a small town and they have capacity.

Hope that helps.
