IT Work on STT/STX

Hi all,
First off, great forum. I'm a 19 year old Irishman itching to move back to St. Thomas or St. Croix. I used to live there when I was around 14 or so, but was dragged back to Ireland on family business. I currently work as a LAN administrator in a major bank over here. I am a dual citizen possessing both US and Irish passports, so visas would not concernt me. I can also speak fairly fluent Spanish. My question to the forum is, is there much demand for IT workers or should I just ditch it and become a divemaster? I don't care too much about making tons of cash, just want to live in the sun and dive often. Also, if there are any likeminded folks looking for room mates, let me know.

Cheers,
Cormac
