Dont think bartending is a possibility!!! Competition with the locals, I live on Caye Caulker never has been even one gringo bartender, However you can own the bar. As far as tutoring goes, we have a good teacher here from Canada, he used to teach at a private school in San Pedro, earned $45 a day, $15 to water taxi, took home $30. He has managed to find one student here whos family has been willing to invest in home tutoring, so it dosnt seem a realistic plan!!!
