C Dub,
did you find anything ? If so PM me.
I am on island several times a year and thus far the only technical diving I could do here I had to arrange all myself. Bring my own O2 booster, find a boat and skipper etc.
The challenges on this island are:
1) Most of the dive sites close to shore on the Caribbean side are only 60-100 feet.
2) There are a few nice sites that could make for a nice normoxic tech dive but they are 1-2 miles out and most of the time the dive operators will run one boat a day and have a lot of folks on board who can / want to do nothing much deeper than 80 feet.
3) No Helium fills or Sofnolime on island.
4) No Nitrox blender. The three major dive ops I know on island are all air-only.
I have equipment here to do technical dives but it's a challenge to find a boat and skipper that will work out in terms of financial viability and safety (like most people I want it to be economical enough to do it 5 times a week, yet safe)

There is only one 5 star shop and you may see me on the boat.
+1. Pro Divers is my go-to op here. Clean boat, fun crew, good instructors and safety standards.
