Another potential source of schooled and talented musicians is the music dept. of your local university (often overlooked when you need studio tracks on the cheap). I did it both in Hawaii (UH-Hilo) and Tampa (USF). I even ended up co-teaching a jazz improv workshop during the summer (great fun). Some of the kids are absolutely scary with their technique. Check it out. They'll quickly let you know which of their peers is "studio ready".
