I know that it will be licensed intensively as well. Depending on where you are. I believe the FAA has oem licensing, but also local municipal/ police/ FBI have divisions that monitor during holidays or events in big cities. I guess it really depends where you are.
It does sound cool though. If it could be you and I assume you need a box truck. I guess, You could even run it with out a facility? Mobil- Generator charging setup & a truck.it does sound like it could really run into some numbers on the initial investment. I don't know factually, but I assume you can't run 40/80 drones off your iPhone. You're gonna need some kind of cellular transmitter device & laptops/ software.
It does sound cool. The only issue I see is your customer base and cyclical sales. New business promotions, holiday events, gender reveals, and corporate clients, I guess also holidays memorial Day, 4 th of July, Halloween, Christmas, thanksgiving.
I guess you need some yearly type show with big outfits and then Fill in the rest of the year.
