Ramond, I'm sure we all commend you on your dedication to this project and wish you success. What we are saying is you do not need to be concerned with the drone portion of the project beyond making sure the company you hire uses an FAA Certified Pilot who can show you his/her credentials. Once they are hired, all of the drone flying issues and permits are handled by them. You can just concentrate on the other many details of your project and let them worry about the proper paperwork and FAA waivers they will need for the flying.
