Replying to Ski Instructor

I'm kind of tired of life in the flat lands of Belgium so I've been thinking of getting my ski instructor diploma this summer or begin next season. Now I've always been skiïng without that in mind and I actually know shit about this. Anyone who can give me some good advice on with what agency to do it, preferably in Europe but I don't mind going to the US or Canada so anything that can help is welcome. Ow yeah I do want to get this and work full-time as a ski instructor at some point, just FYI.

They told me the Swiss one was pretty good, and I've got some information here about http://www.skiacademyswitzerland.com/ what do you guys think, to expensive?
