Arizona huh? Hmm... UTI or Hot Rod Institute is out there in Pheonix (forgot how to spell that all of a sudden, lol). A lot of people tell me that Hot Rod Institute isn't worth the money and all... not sure why. Another school to look into is Wyotech in California. There is a couple posts on this already you maybe wan't to search and read on. I got your email addy and will IM you when I see you online and talk to you further on this. Don't be surprised when most people here tell you not to do what you wan't to do, becaue you have to be 150% dedicated to what you wan't to do and can't back out. It's not easy either....
This might have not helped you out any and sorry.
