How can i get started in the career as a golf instructor and what is an average salary?

and are there lots of jobs to be had? i live in Europe and thought about going to America (I'm an American) to get trained/certified for a year or 2 then come back here to work. Seems where I am in the Czech Republic golf is just getting going. potentially a BIG future business here. but if i decided to stay in US after some training, are there jobs and is it a good career decision. i would really like some feedback please. you can email me at: 73matarazzo@gmail.com or find me on skype (username: ducaticanine)...thanx.. and please give me some info as to getting PGA certified or not.. seems there are many avenues to take... thanx again :)
