Got hired as a drone opp on a film crew. Have commercial license, looking for backup drone.

I have the Mavic 2 Pro and have flown it a lot over the past 6 months. I flew the Phantom last summer in Montana pretty consistently, but don't have access to it anymore. As the drone opp, my worst nightmare would be my Mavic 2 failing and me not having a backup to finish the job. But now that I'm doing more research, I also want a camera that I will be able to get great video (4k) with and fly indoors. A little overwhelmed and would love the help. via /r/drones https://ift.tt/2OmTru1
