T-shirt designs

I'm trying to find a way to spice up my t-shirt selection. I've got a bunch of ideas chicken-scratched out but I'm no artist. I thought it would be nice to find people who could turn those into viable designs. I looked on Spreadshirt and Threadless but came up empty.

Mr. Coulton recently had a post about a collaborative t-shirt design site. Which would be sweet but is obviously a pretty rough thing to set up dealing with paying out royalties all the time.

I'd be satisfied if there was simply a site with talented t-shirt artists I could buy designs off of easily.
