I'd concur with Scenic. If you had 500 hours, I'd say get a VFR 135 job in the canyon, that's what I did.

Anyhow, even with your times, you could probably eventually get on at a regional. You could do an RJ course and just buy your way in. Sadly, it's all the rage these days.

I also believe in the CFI as a way to build time, experience, seasoning, and develop your aviation skills. I can't tell you how many times I've heard guys say "I'd suck at it, don't want to do it". Then, they are forced into it and say what a great learning experience it is. To each his own, though, I agree that the last thing a guy should do is become a CFI if he's dead set against it.
