I'm not convinced that there will be anything to deliver from East to West over the Atlantic.
West to east you will probably need an FAA commercial licence.
You will also probably need to have already done the flight before. Rumour has it that the Canadians will not let you leave their airspace en-route for Greenland unless you have previous route experience (could be wrong, but I've heard it before).
Next problem is insurance. Without some experience on the aircraft type (not just a check out) and on the route...who do you expect will insure you to fly it?
<<<edit from here>>>
Forgive me, I've just looked at your profile...it will be an FAA licence - but it still won't work without route experience.... and to be honest, I would expect that a brand new FAA Commercial will not help matters.
Sorry if you think I'm being mean.
