I tried my best to figure out how to close my office and live the dive life... After a little research I realized I'm not quitting my day job. There's just simply very few ways to find treasure from the ocean.
If I were going to do it, I'd probably go the Six Pack route. I'd try my best to have a charter that caters to fisherman, scuba divers, freedivers, spearos, tourist cruises, etc. and ultimately just make sure everyone has a lot of fun on my boat on the water and can't wait to book another trip.
But to do that requires a lot of diving, fishing and boating knowledge, licenses, certs. and insurance, entrepreneurship spirit, dedication, hard work and know how and the realization you're probably not going to get rich doing what you love.
