This is a simple commissioned illustration agreement. I sometimes have my DeviantArt / Expo clients (including international clients doing business with US persons) use contracts like this when asked to do character illustrations, avatars, etc...
The contract fits on one page if you print it small enough. It is pro-Artist -- a flat, non-refundable commission fee is charged. ALL RIGHTS are NON-EXCLUSIVELY licensed -- the purchaser can do whatever... show more he/she wants for as long as he/she wants (so long as he/she doesn't pretend he/she is the artist), but Artist also keeps the rights. But because most people want a "unique" and "special" piece of Art, the Artist agrees not to resell or publish the art, except for use in a Portfolio (such as posting on DeviantArt).
Dispute resolution is through internationally enforceable arbitration.
For a commercial (business) purchaser, you will want to use a longer, more complex contract.
As always, write in forks as you agree, and bear in mind this is a GENERIC TEMPLATE designed under United States law -- run it by your own attorney!
