Where do i Request Character Designs?

Not sure if there ifs a forum for this or if this even goes in the artist show off section but i was wondering if there are any threads where you can put in a request for a character design and people submit there renditions. I have a Series of Unique Characters with different power sets but get too frustrated with my own horrible drawings .

You can just turn this into a Request thread mate if you want. Post names and pics of your Characters and other people willing will draw them for you! :D

@greggh: I'd give it a shot given details. :)
