Search harder - theres plenty on this subject. If you want to get hours and a JAA CPL - Then DO NOT do the HAI JAA course. by all means go there- its a very good school, but it is also the most expensive JAA groundschool anywhere in the world (that i've found) - just go to heli.com and check out the prices. do total cost minus flight time costs and you'll see.
much better to get FAA CPL, then come home and do JAA theory after, or even before you go. you can then convert to JAA. If you plan to go there and instruct, then FAA will get you building hours far faster and far cheaper - the course is shorter, which means in the same amount of time you can come home with more hours.
