Looking for fighting game art for RPG

[drkrash]

I am presently writing a tabletop role-playing game about the adventures and exploits of manga-style martial artist characters as found in fighting video games such as Street Fighter, The King of Fighters, and Guilty Gear. 

I am looking for a piece of art that I could license for a single use as the cover for the book.  The book will be available on lulu and drivethrurpg as both pdf and print-on-demand.

I need something color, 8.5 x 11, with some room in the center top for the title, and scanned at 300 dpi.

I'm flexible regarding the specifics of the piece, as long as it conveys the idea of over-the-top manga-style martial arts characters and/or combat.  Characters in the piece could be posing or fighting.

For obvious reasons, I cannot accept any licensed characters, or even images that too closely resemble licensed characters.

I apologize that my budget is very low for this project.  I am willing to pay via PayPal for use of the art.  I'm trying to keep my budget around $40 for this single use, though I have some room for negotiation if I really like a piece.  Of course, full credit will be included in the work.  I anticipate the book will be finished and available in Spring 2010. 

Please contact me via email at drkrash1969 at Yahoo if you may be able to help me out.
Thanks in advance for your consideration.

Sincerely,
Christopher Peter
