To begin with, you need to buy a quadcopter for aerial photography because the main ideas for making money are related to video filming. Before you start earning money shooting from a drone, you need to hone your skills.
My main activity to make money with Drone is shooting as an additional camera at events - weddings, large parties, banquets. I've also been involved in shooting commercials a couple of times.
It's an interesting experience and so far my extra income. To make money just from drone photography, you need to advertise your services and keep pages on social networks.
