Been around the world a few times the last 7 years, came home with FAA tickets and appx. 2300hrs and experience from different continents.
Hooked up with yank registered King Air and fly that every now and then, looks like there a quite a few N-reg planes and not that many experienced (read: with your kind of hours) pilots to fly them in Europe - insurance companies have their requirements, have you thought about the corporate scene??
Best of luck
