I'd offer you the skills I've developed through my indie video game developing experience (Thus involving every sector of video game development, and scenery-design), although my offer is limited, as I've mostly worked on indie projects, so the art style may vary on what has been made already, if you could describe me what kind of graphics would it be required (Such as realistic, cartoonish, dark, retro, 8-bit, 16-bit, etc), then I could specify whether I could do such designs.
