Hi there!
I hope you find your illustrator soon!
But for now some questions!
You need the illustrator to do the whole thing, as in -storyboard, sketch, lineart, color, letterer-, or only the lineart?
Also it would be nice if you add the links for a couple of things, like your comic and a download file where posible illustrator can make some doodles for you with your following some requirements, to ensure the quality of your webcomic. Like one of the file used from your illustrators, for example.
Also, giving some reference for the paid wouldn't bother at all, ha!
