First of all, Congratulations on your first green screen room.
Even though I am new to this platform, I have a 4 year work experience in the field of video production. As a former University lecturer, handling green screen courses among others, I think i can help you achieve what you are aiming to and get a clear green screen room without shadows.
Hire me and we get this think done. I am also willing to do skype guide if need be.
Happy production!
