If you know a good technical person you trust, ask them to help. If you don't, go make some technical friends. I've been helping screen technical people for friend's companies for a while now. My friends trust me to determine if someone is the right fit for the role, technically. I'm too busy on my own projects to work for/with my friends full time, but I can spend an hour or two doing phone screens, interviews, reading resumes, etc... Some of them even pay me for it:) There's no magic formula that lets you (a business guy) figure out who's great, who's really green, who's full of crap, etc... It can't be done. You have to rely on a web of trust, using your friends.
