I agree with a lot of the concern about some of the negativity but also with @L&L DRONE VIEWS to stay positive and it is still early. Dronebase and Droners.io are tough because folks are willing to do that work for so cheap (more of a concern on Droners.io IMO). Also, I know a lot of people locally who fly commercially without a license and they are canabilizing some of the business as they are willing to do it cheaper than I ever would.
I would stick to your pricing and show the quality of your work. That is what I have done with my repeat clients and it has paid off. Do I make all of my money from my drone - no. I am lucky to do ground photography and have a successful business there. That said, I enjoy the drone work and know that if I was 100% focused on it, but sticking to my pricing and showing the quality of work to all of the available clients (while perhaps supplementing with Dronebase and Droners.io at a price point I was comfortable with), I would be successful.
Clients are still figuring the drone thing out as others have said to include cost, quality, etc. As such, getting in now and pushing will lead to success.
