He rarely does clinics any longer, Olympic archer coach and avid recurve/LB hunter, Tim Strickland would be my choice if I wanted help.
By the way, most of these fellows know each other pretty well. You'll hear interesting reports about their methods from their "competition".
The one huge RED FLAG for me if I were considering a coach would be to know whether or not he/she has on-going Target Panic. Believe it or not, some who teach, do. Past tense is ok but on-going is not. Correcting and preventing TP must be among the instructor's ability.
