I believe that just about every business, operation, teaching academy, dive resort, etc., is going to HAVE to have some kind of networking infrastructure, not to mention an online presence, to be successful. I don’t think there would be a whole lot of big opportunities that would offer full-time IT jobs with the exception of working for a large manufacturer like Scuba Pro, but a bigger operation (like the dive operation at an all-inclusive resort) might have opportunity for someone who could fill an instructor/divemaster role who also is keen on network management, setup, security, etc. "Why yes, I am a MSDT and a CCNA..." could be a powerfully commanding set of qualifications. Just my thoughts...
