Any dive operator will arrange private dives or lessons for you. There'll be a minimum charge for tying up the boat, captain & guide - usually around the equivalent of four normal divers, but some operators charge more.

Will you be staying that far north, or were you just considering that as a possible safe area for kayaking? There are several operators up that way who'd be glad to help you - if you tell me just where you'll I can suggest the best for you.
