Know-How Exchange : Taglines/Names

I am creating a promotional advertisement for a printing company that is geared specifically to medical, healthcare, and pharmacutical authors and editors. We are offering a discount of 20% to order a reprint of one of their previous articles.

Due to the conservative market I was thinking "It pays to be valued" or simply "As a valued author, accept this 20% discount...."

Also, I am having a problem deciding on an image. Should I place an image of a proud author/doctor, combo of books and money icon, or nothing at all.

This helped before, can you help again?
