Well, to start, posting the question anonymously means that nobody who actually does this sort of a thing for a living can contact you :-). Not sure if that was the intended effect or not.

I run a 25-engineer development shop in Colorado named Cardinal Peak (http://www.cardinalpeak.com). We do quite a bit of development on OS/X and Linux, including open-source development, and I'd be happy to talk with you about your needs.

Please forgive the obvious self-serving nature of this response, but it seemed on-topic for the original question.
