Hi
You say you are not interested in building hours for the airlines, if that is the case have you considered converting to microlights and getting the instructors rating? Im not sure of the exact procedure but with your experience im sure it would not require much.
The reason I suggest this is because I have been told there is a shortage of microlight instructors out there. They also get paid more than group A instructors although may not fly as much due weather.
Just a suggestion, if you want to be paid to fly then it could be the way to go, for me a microlight strip in the spring/summer would seem to be a great place to work.
