Mark, it is difficult to find coaches....it wasn't thirty years ago; however, in your state of Alabama, I'm sure there are many older archers who competed and are capable of teaching archery form, and that's basically what is needed. Most guys who shoot badly, lack proper form, and it only takes about five minutes or so to correct the basics.
Guys coming from shooting compounds actually are better equipped to handle the change, since they are probably understanding of archery form. The basics don't change much, but the devil is in the details.
Also, much can be garnered from books, such as Jay Kidwell's treatise, and some older ones that can be found via places like abebooks.com.
