OK, perhaps not exactly, but it should at least be on the short list of books in every designer's library, and that of anyone engaging in the business of selling hand lettering or calligraphy -- there's a section in the book just for us!
What am I talking about? The Graphic Artist's Guild Handbook of Pricing and Ethical Guidelines. It is helpful to have several of the past editions as well as the latest, as each of the books has different reference tables that I find extremely helpful when pricing, especially for commerical work. Make sure you get yours soon!
