Graphics work for an online comedy series

I'm developing a new web comedy, where the lives of a mismatched group of misfit gamers are thrown into even greater disarray by the arrival of an AI gaming 'bot' who tries to shape up their skills and step up their achievements. I'm looking for people with graphic design skills who can contribute assets that we can use in each episode (e.g. game information like speedometers, game character pictures, retro pixel art). We're also looking for an overall graphics supervisor, who could work with our director of photography to make sure we frame the action in a way that best supports overlaying visual assets in post production. My budget is extremely tight, so any payment is likely to be token at best.
