Thanks for inquiry, Jeff.
I'm Bill Taylor, a professional photographer and Part 107 Certified Remote Pilot based in Gambrills, MD, in the heart of the Baltimore/Washington/Annapolis area. I have been doing roof inspections (a few dozen) under the auspices of DroneBase. I would love to deal directly with the end customers.
I have a Mavic Air and soon a Mavic Air 2. I also have part ownership of and access to a DJI Phantom 3 Advanced and DJI Phantom 4 Professional.
Feel free to contact me anytime.
