GezHeli,
I was working as an instructor in Ireland resently for a couple of years. It's seems that the Irish helicopter industry is expanding (booming) very rapidly at the moment (might be a good time to go for your training).
In general there is two way to go;
1) Do your training in Europe
2) Train in the USA and then convert to JAA licence
It's pretty much up to you which way suits you best. Take contact with some of the well known flight schools and sort out what kind of deal you will get. If your goal is to work in Europe then doing all your training in Europe should be a good and very strait forward option (if you can finance it...
). On the other hand if you are interested to see whats going on in the "big" world and maybe looking for some kind of adventures as well, the USA route might suit you.
Whathever route you are taking it's going to take some years and plenty of work to get to your goal, so be prepared to work hard.
I was working for Blue Star Helicopters in Cork, contact them and I'm sure they will help you. Also ask to get some of the students telephone numbers who are going for CPL and ask them what the situation is at the moment.
...and, don't give up your dreams!
