Get all the official licences and . .

yes,surprisingly perhaps it is regulated, so you will need a tourist licence and a marine licence along with insurance.
I have no idea where you get these, but some friends have just started a wakeboard business on the Yasica and had to comply with these requirements.
Consult an attorney.
Go to see the local chief of police who covers the area in which you are interested in working, he will be able to let you know if you have any chance of infiltrating the area, others already there will be paying him to ensure the likes of you are removed if you 'interfere'. If there is scope for you to work the area then he will tell you. A retainer will ensure you don't get molested by either people wishing to offer protection or the local police, or are they the same thing? LOL... Anyway I simply wish to point out that business is not done in the way us westerners would usually imagine.
Last thing, Jetski's - nice and cheap in Miami, transport to DR not too bad, getting them out of customs without a Kings ransom, forget it. But there are ways round this, but I'd be an idiot to tell you sorry, I'm bound for that direction myself in about 3 years.
Good luck anyway
