I live in Nassau Bahamas and would be very interested in your venture. Last month i pulled up an 11foot anchor that predates 1780. I am in the process of searching for a wreck around the area where i found the anchor. I have a Bahamian residency with the right to work. However Dell is right about the gov't not giving out any treasure hunting licences at the moment, but the Bahamas is a country where it is fairly easy to pull strings, and if you pull the right ones anything is possible.
Tight lines to ya, Jim
