Andrew Driver from Blue Foot Diving (Blue Foot Diving - Andrew Driver) is a Rebreather Instructor Trainer with IANTD out of Alex Bay with a vast experience. I'd give him a call.
My wife and I used Blue foot diving last season. We used open circuit and there was another tech diver with a closed circuit. It was a nice friendly and knowledgable group. You can check out their website bluefootdiving.com.
