Granted I'm not into agencies, and certainly there are guys who've been on this board longer than I have.  But you might want to try tineye.com to verify the pics of some of the ladies. Anyway, I've attached the list of the top 100 providers for Phoenix. Say what you want about the top 100 list, you really can't go wrong with most of the ladies on the list. Just a personal preference as to what you like. Good luck and spend a lot of # while you're here, the Phoenix economy can sure use it.
