Who does transfers????

Does anyone have the URL or phone number of a UK company which will turn an image into a transfer (ie applied like a fake tatoo) for me?

I'm gonna get a new computer case, and want to put an image on the front without paying for Airbrushing. If anyone has a better idea than a transfer, I'd be happy to hear it.

TIA

Cool Case Mods do some, I've discovered, but I'll have to contact them to see if they do custom designs..
