Ill keep beating this dead horse, but only because I have been there and it worked.
Sheble Aviation in Kingman. You are looking at a 10-14 day course for all three ratings in your price range.
Wherever you go to work will teach you how they want you to teach. You will not always agree with what they want (like landing full flaps regardless if you are in a 172 and it is gusting 35) but they cut the paychecks. Just make rational judgments when you get there, because you are the final authority in the cockpit.
