Newer R44 pilot  

I was asked by my employer (mom and pop) to do a flight this Xmas. I guess the customer is paying decently. I am concerned about the practicality and safety of it. Its a photo flight of sorts. 

The job is to do a running landing at about 25 kts ground speed on the property owner's frozen over lake while he simultaneously drives a Ford Raptor (very nice custom) the opposite direction towards the sunset. He has arranged for a 21 gun salute right as the helicopter is about to touch down while the truck accelerates in the opposite direction. The truck will have a large USA flag in tow. Thing is the flag is like 20 feet high. He keeps talking about how the truck is short enough to drive under the rotor and that he wouldn't be "caught dead" having his "boys" shooting blanks so he is using live ammo. Should I do this? Seems really cool but still.
