Hello! Although not currently located in the US, it is my native tongue, with experience on-camera from local english-based theaters and small news publications. You can rely on me to give a proper explanation for anything your product needs (greenscreen included, of course!). Although new to this site, give me a chance to help you. I hope you consider me, and if at all interested, I hope you read my profile.
P.S: You're free to message me anytime if you have any questions!
