This might be for the guy that started this thread but let me just say I wanted to do the very same. Start an aerial photography business. I have (but it's fading into HAD) every intention of getting the FAA Exemption. I just wanted to test the waters first and see if there might be a market in my area for a small start-up aerial photography business. So, I went gung-ho on it and registered a domain name, printed up business cards, designed a flyer, invested in things that I felt would help my business. I started mailing my flyer/business card to real estate agents. About a 100 were mailed out. Out of the 100 flyers I got exactly "0" calls. My website has a quick quote capability that can email me should anyone visit the site and that got me exactly "0" business.
So yeah I was quite surprised that not even 1 person out of a 100 would be interested. I checked some of the local Real Estate listings and what methods the Agents use to list homes and when it comes to Aerial views they all seem to use that FUGLY Google Maps. I don't know if they just don't see a need or value in Drone Aerial shots or not. I have several examples I posted on my site that they could see would look 100x better. Maybe they just haven't bothered to look. I do have someone who is a Real Estate Agent that I plan to talk to next week so I can ask these kinds of questions. .
I gotta tell ya though I'm no longer gung-ho about running out and investing $5k into a pilots license just to get "0" more clients.
Something for the OP to think about.
