Well Pitchka, two questions:
Where did you get that "expert pilot" from? It looks like nobody here has ever heard of it. Anyway, whatever this might mean in Canada, it might not mean anything in any other country.
What is limited VFR? Special VFR? Does that depend on the number of hours in Canada?
If you already have sufficient funds to buy a helicopter and fly it for training for 500 hours - which I think is not a very clever idea, because your ship will be down for maintenance a lot - why don't you move to Japan a do your training there with a local company with their helicopters? You swat several flys with one stroke. You learn the language, you learn the system you want to fly in, you get contacts in the industry, you get experience dealing with the government ... and when you have all your tickets, you can start the company. Provided Nippon lets you stay.
