Graphic Designer for Custom Backdrop Scene

We are in need of a custom backdrop for Podcast Recording. At the moment, we have been using a stock backdrop from an online store and are ready to move to a more custom option. While we hope the new one to be a nod to the original, we are ultimately seeking a graphic designer to collaborate on a digital file that can be printed onto a backdrop for screen use. The graphic designer needs to be versed in creating realistic environments (in this case, a vintage laundromat) and preferably someone with a history of designing these elements for on-screen use (taking into account lighting, shadows, etc). The overall backdrop would be roughly 15ft(w)x10ft(h) (or smaller) and we are seeking a digital file that can be printed to that size in a high quality for use in a podcast online. While this is a one time project, we might have graphic design opportunities available in the future.
