Fred is a professional photographer, most of us aren't. One thing I disagree with. If you are flying a drone, your first obligation is to fly it safely, photography although critically important is second on the list. Of course I think that way because I'm a pilot and not a professional Photographer.
If I were you I would look into construction documentation, you still want good quality pictures, but you don't need to be at the level that a professional photographer is. If you wanted to work for someone in that field I would check out Multivista in your area. Not only that if they hire you, they will send you to a school in Huntsville and they will teach you how to fly, and fly well.
Most of the Multivista branches use the Inspire 2, and the Phantom 4 RTK, and they supply the drones, they also supply a Nikon D500, and a MatterPort. They have plenty of photography training as well.
I don't work for them, but have contracted to them several times.
