In games like ffxi I have seen great work done by the community making custom 3d models and textures. many cases looking better then what was in the game.
I know as an indie company money might be tight. so i suggest adding a section for these people to upload their work to be reviewed and used in the game. many people would do this just to see their work in a game and put it on a resume.
I am not a graphic artist just had the idea while looking through old screen shots of ffxi and remembering most of what i was looking at was made by the community.
ps i know not all work that would be uploaded would not be good but you would be surprised what could turn up.
