Dear Danmansell,
If I were You....
I will probably try to find position in Asia on R22/R44/R66.
So firstly visit RHC website and try to find R44 dealer in Asia who is from UK
You will stay there for 3-5 years to collect 2000 h, maybe You will fly in SE turbine.
During that time validate Your EASA licence to FAA. Air Methods has just ordered 200 new helicopters.
After 3-5 years of flying You will see what could be the best option.
I think flying offshore is nice paid job, but EMS/HEMS is better for Yourself. You can serve Your people, You can help them in the way how well You are with cyclic and collective
I hope You can find Your way.
