Well It's great to have ambition but perhaps you are setting your sights a tad high at this stage, C150 - kingair <100 hours?
Are you aware of the performance of an aircraft like the Kingair?
Unless you have a shed load of dosh and you intend buying your own one (doubt the insurance company would let you) then I would love to know who is going to let you fly one?!
I would suggest if you have your heart set on flying the kingair, you either work at getting your ATPL's and all that goes with them, get the experience then apply for a first officer job with Gama or somebody like that.
Or, you could do the FAA licence, find a kingair on the N reg (no type rating) , and try and blag your way into the right hand seat.
