Tropic air are a good outfit. The maintenance compared to the rest of Belize is good too. Bases are in Belize city or San Pedro, Ambergris Caye. San Pedro is the one to go for if given the choice. Not sure about pay but they get pay for time first officers from the USA etc and so don't bank on getting paid much as an FO.
Good VFR experience but only day flying.
Hope this helps.
