I think he means trying to make a proof of concept to get an artist to do the work.

If I ever get round to making games, I will need an art guy and a sound guy, because I know full well I cant do anything remotely good there. But I cant afford to pay an art/sound guy, so theyre not going to just do work for a random guy on the promise of a cut of the profits because what profits? I’m just a guy with a dream and a promise.
