You're killin' me! The FGBNMS isn't in the business of training divers, and I know of no instructor that operates off the Fling or Spree, the only operators who consistently ply the FG. Besides, I don't know what the requirements for skill tests are, but I have a hard time thinking that they could be performed in a place where there are no platforms, landing on the bottom is off-limits, the current is sometimes powerful enough to rip the mask off your head, and to misjudge where the boat is means the next stop is Galveston (100 miles away). In fact, ALL of the sites you mentioned (the ones where I dive, you noticed), are just as I stated...each is a full day travel from my location. When I couple that with four days to complete the course (I'm guessing on the timeline...it took about that amount of time just to get my AOW, so certainly a master diver cert from NAUI would take at least as long), that's about a week of time that is quite simply out of my reach except under the most extraordinary of conditions.
