So you have a few options - one would be to split profits with an artist (usually you would need to have some fairly well working code for an artist to take the risk). Another option would be to use resources like Open Game Art - http://opengameart.org/ http://opengameart.org/ and supplement as needed (but of course be mindful of licenses). Third you could use primarily geometry, or procedurally generated content, or ascii. I think finding an artist willing to partner up is the best bet.
