It is worth mentioning your exdperience and quals as above to Sunsail - if you're willing to spend a season in the sun then they are a good employer for working the beach at their beach club resorts - long days hard work but something I wished I had done when younger, even if just for one season...
www.sunsail.com for info...you may also have to be 18 but not sure on this one...they're helpful so give them a ring - nothing ventured...!
They do require safety boat Dinghy Instructor etc so it would seem you are well on your way..
Just thoughts,
Gordon...
