Teacher Discussion Forums

hi hi. i found this really functional web page, where i can find some answers that i need... me and a friend, we are developing a language-courses web page, and it will be interesting for us to know, if there are statistics, about the amount of language teachers, or language professionals in the wolrd, at least in some regions.... It´s the idea, how many people work in the industry, or have something with it... Hopefully somebody can help us... thanks a lot
