Lot's of options for you, with several in AZ (always nice if you can drop the rifle off in person and talk to the gunsmith face-to-face.)
But on the off chance you are still looking, one of the best gunsmiths I've ever dealt with is CHARLEY ROBERTSON at SCORE-HIGH in Albuquerque, NM. Rem 700s are his specialty, though he'll work on most rifles. What I like about him is he is so meticulous and has this inner compulsion to 'do it right'. He just can't let it go out the door if it isn't perfect. I like that!
