marine mechanic??

Hi Everyone,
I’m new to the board, been going through the posts. We currently have our business here (Montana) for sale and plan on heading south asap. If the business doesn’t sell this year we still plan on heading south for four or five months and then back here to tend to business until it does sell. We spent four months on an island this winter and loved it. We looked at starting a business on Roatan but jumping through their government hoops might be too much for us. We can retire there but not work there. We are too young to retire and don’t really want to yet. We just want to slow down a little. OK, here’s the question, Dick is a factory certified marine technician, is there any need for a marine mechanic there? He has 25 years experience and thirteen certificates of schooling.
Thanks,
Juanita
