Instead of hiring a developer that would drag you down, did you consider offering more money? When people say there's a shortage of developers, or that they find it really hard to find developers, my guess is that they have to add "at the salary I'm offering" to the end of the statement.
I was car shopping a few months ago, and I found there's a dire shortage of brand new $10K BMWs.
