Best I could find with a quick search, but you need to buy some credits to download it:http://www.vectorstock.com/royalty-free ... tor-722034
However, that's a very clean image you have there, so it would vectorize very easily. I could give it a shot later if nobody else has one already. Would go even better if you had a higher-res image.
