I don't get what's wrong with this. At least the requester has some idea of what they want, and it makes sense to me. They just don't understand some basic things about our industry (like "blacker blacks"), nor should we expect them to.

A few minutes on iStockPhoto, a few more minutes in html/css, and you could be done.

Maybe I'll email them, I've already found a couple of candidate images on iStockPhoto.
