Hey mate, you still looking for a signature artist? I can highly (shamelessly even) recommend SPQR. If you PM him nicely he can generate what ever you like. I can vouch for his skill, below are a few he recently did for me + my actual sig before that!
The design has my local football club emblem and shirt as tabard (a little request I wanted in the art). Proves he will help you get what you want!
