Copterin,
Ignore those first 3 posts.Those guys are obviously worried that you will succeed where they didn't.
Do what you need to do to get a start. I am sure you have herd the saying, "nice guys get nowhere"
Unless you are prepared to be passionate about instructing then dont do it.
My suggestion is to come over here with an R22/R44 endorsement and head up north during the winter.'
Be aware however that it may take some time to get your licence converted as the security checks that you have to go through are quite lenghty. Sometimes up to a 2 month or more waiting list.
Good luck
