Greg’s right this sounds like it would be a blast, maybe you can offer a deal where folks can come while on vacation an help out, if you find something while there you get a cut. That way you don’t have to pay folks to work, you get free help and if lucky enuff, those who are present if anything is found get to reap the booty. Hell I’m ready to take a vacation and come down, God knows I need one. Even if I didn’t find anything I’d still enjoy the diving and experience of helping on you boat.
