Whats really out there for any pilot that does not want to go that route and wants to remain in GA as a commercial pilot without being an instructor?.
Why on earth would you want to do that to yourself?
I can understand RFDS; or career in Ag but to remain in GA charter as career??!! You would be better off in every way by going to a regional airline. You will get paid more, the equipment is better, the conditions are better, you will get a roster. None of which exist in GA!
Also consider the fact that GA aircraft are already very very very old and noone is really buying new gear except for the odd Caravan. Which means you will be still be sitting in the icing zone, and in the weather.
Corporate jobs on jets usually hire airline pilots and the corporate Turboprop jobs usually hire RFDS pilots or someone know to the owner.
One possibility is Survey but that would mean long periods away from home often in very remote areas flying GA aircraft. Again all things out together you would be better off in a Regional.
