Maxialphas,
Worrab has a point with looking in the yellow pages, there will be quite a few photographers out there and most instructors are tied to a flying school.
Alot of photography business I would imagine comes from Word of mouth/recommendation so to establish yourself to get to that level may prove an uphill struggle. The same applies for an instructor not tied to a flight school.
In my own personal view for decent business marketing I would forget the 3 years course and employ a marketing agency, this will probably work out cheaper (over time) and much quicker to get to where you want to be. One of the things I have learnt running a business is not to stretch yourself too thinly by wearing all the hats - employ contractors/agencies/accountants when required as they have spent years doing what you will have only scratched the surface at and will no doubt do a better job. Speak to a couple of angencies about your ideas and see how much they will help and charge you.
