Which Type Rating

[pumpkinhead]

I may have an opportunity to pay for a type rating, I am partial to the B747-400 but that’s just an aircraft I always wanted to fly. I wanted some feedback on what aircraft is in the most demand, (what might secure me a job), both wide body and narrow body. This would most likely be for a foreign operation. Also if not too much trouble, recommended school for such aircraft training. Thank You.
