unless you are from the Caribbean you won't find much with low time, keep in mind that most Island flying is done in single pilot twin engine aircrafts, two things you need here: good amount of multi time and PIC, most places won't hire you with less the ATPL times. If you are French you can try in the French Islands, there you can use your JAA. Most low timer jobs are not that cool either, unless you like to do 6 times a day Curacao-Bonaire there is not much you will see..
Before you even start thinking about getting a job, get your licenses and focus on that...
