Mine was done by a former player who offered commission work from her DeviantArt page.
However, that person doesn't play anymore and has removed the commission info from her site.
The price was extremely low.
There are lots of artists though who offer this kind of thing on the internet. Try using Google to locate DeviantArt profiles which offer to do commission work, or, just Google for "find an artist on the internet for commissions", and pick someone who reveals their price range and a portfolio which matches what you're after.
