Dan Dvorak has been building stuff like this for longer than most anybody. I would use him in a heartbeat if he is close enough to you. I never bought a thing from the guy but did have a couple of phone conversations with him back in the mid eighties and he gave me some great advice.
I don't think you could go wrong there.
