Hi there!
I'm able to clean the background for you, i'm also a filmmaker and video editor. It will be required that you send me some prints with notes of the objects that will be removed, as the light plugs and etc, but some art paintings adds a good wight on scenography, keep it in mind. I can make you a five seconds free test, if needed!
Feel free to send me a message if anything is needed.
Thank you!
