What are the needs?

Thinking about moving down to St John in the next coming year.  I am currently a licensed Plumber and General Contractor.  I am seeing if there is a need for plumbers and general contractors in St John.  Also seeing if there is any other needs that anyone knows about that I could bring to the island.  Moving down there with a friend that lived on St John in the 90s and early 2000s.  So island life and the daily life has been explained...Just wondering what the work is available for a tradesman that will own his own business.  Thank you in advance for any input.
