Dennis et al,.
As has been mentioned above the key to this is marketing. I also think the marketplace is qualified ppl(h) pilots. I would suggest you devise an 'Advanced flying' course with your own certificate at the end of it.
Marketed in the right way and place you could charge considerably more than a standard hourly rate. If you want more info/help PM me it would be a very interesting project to work on.
