Hey! Welcome to MT. I'm glad you like the place and it's people.
As for your question; Minitokyo has a hand full of freestyle artists that share their work. It is to share what they
love and improve in it aswell regarding art. There might be members who are willing to take on the job and make some
money or other purposes.
Your biggest chance is the Indy-art section, because there are many artists with original art and their own style.
Unlike the wallpaper section, where there is usually more scanned or vector art than original. I suggest you look around
the gallery and give some artists a guestbook poke and see if anyone is willing to give it a chance. Not every artist
goes around the forums, so you better not try. A personal approach is overal better, but be sure not to make yourself
look like a...you know...it sometimes happens!
I do want to mention, that MT and it's staff does not have any addition to it's member's decision, but does try to keep
people's copyrights legal (distribution without consent is a no-go). So, try your luck and see if you can find someone.
