For as little as I know about this subject I'll past it on. If you are to teach English for someone else your problem is they don't pay very well and you will only work when they have the work. You can charge more money teaching Spanish to foreigners. If you have the capitol you can open your own business ($800 US for the company etc) or just start by placing adds. You might teach English to companies (I have not heard of anyone doing that), hotels, timeshares, restaurants etc. This will take some doing as the response time down here from companies is like when your sister asks you to her borrow your favorite 501's to go camping for the weekend. As for working in a major school, don't know. Have no idea what they pay.
