A Kingair, is a "small aircraft", however TR is expensive, and without experience on type you are on a hiding to nothing! Most ops are single pilot, most insurance companies require at least 700 hours on type, before you can be PIC, so must be with a company that ha approved multi - pilot ops on the King Air, let me guess in Africa, might not be to many who cares about that!
A Kingair, is probably a more demanding aircraft to fly than a Boeing, so how can that be an ideal aircraft to learn for a low hour, 250 hour pilot!
Still there are to many types to guess what to do!
