Ordering an Artwork or Contact- List to Artist, Price?


Hi Guys, i just wanted to ask you about my biggest style problem for my MadCatz SE stick (and maybe future sticks) .
Where can i find and order artworks like i see on masses in several threads here? I dont mean a already existing artwork, but instead to give an artist the order to make one for me of a special character from my favorite game “Garou: Mark of the Wolves”.

Also if someone knows a website or has a list , which people are artist for this case and how i can contact them?

Last question: What would such an artwork costs? Not the exact price , but some example or a an area from cheap to expensive.

Sorry for my poor english ^_- !

greetings Ress
