I was just doing a Google search to try and find an illustrator that would work with a TG theme. As a number of artists at TG Comics work on commission, the search I used was "TG comics illustrator hire."
The only relevant result was this blog!
I have, by the way, found someone that will work with me. His name is Ethan Young. At some point when my financial situation isn't quite so dire, I would like to work with him. Until then, the search goes on for an affordable illustration alternative.
