There's 656424 square miles of area in Alaska, including water bodies (float planes) and winter may require ski's. That's a lot of area so there is a LOT of bush pilots. People do the bush pilot thing until they can get on with a major carrier and fly heavies. If you like something in between, there is a lot of Air Cargo that use things like Electra's, DC-6's, L-100's, Sky Vans, and much more (sorry, I'm not a plane guy, I don't know what these things are), and even old bombers used for firefighting. For a small plane pilot, this is THE place to be. Good luck. You might end up being the pilot of the plane that flies to where I work in the bush one day. See you then.
P.S. There are many I didn't list to include cargo and tour companies, I was just flipping through the phone book.
