Looking for graphic designer to work on game

I wasnt really sure where to post this but me and my brother are creating a Top down shooter game and are looking for artists that want to help. It is a volunteer job because we are not making money off it. Its just a fun project. We need someone to create… Rooms, zombies, players… etc etc… The game is basically 2 players trying to survive in a maze of rooms and halls… Players are board doors/ openings and shoot weapons. If you’re interested reply.
