So some things you are going to want to consider is what can you do; well enough to be paid, it is easy to plan a drone company but your going to need to find a market niche and keep working at it. Luckily you are already in a great place for learning the DroneDeploy side of things and can get help on the mapping aspects here. You might consider also involving yourself in some other communities as well. I have a had tremendous luck and help with the community over at Uavcoach.com, and their associate part 107 test prep site dronepilotgroundschool.com (in case your in need of the license in the us).
Its good to be aware of your regional competition (ie if everyone has a drone business that handles real estate photos and videos you might want to steer yourself in a different direction. A to what pays the best, well this depends on region, but in general the more advanced or exclusive your producible s are the higher you will be able to charge. The flip side is the more you charge, the more expertise your client is going to expect. I cant tell you how many people i talk to that are dead set on finding the highest money they can and want to do surveying, without realizing to be a surveyor requires licenses in it of itself. What you might find is to partner with existing companies to provide the services if you can and build your business out from there.
Another consideration is that flying is by and far the smallest part of operating a commercial drone operation, lets say 5% the other 95% is dedicated to producing your product and running the business. It is always good to keep this in mind when you are trying to find what you can do best.
