Just thought I'd direct your attention to a new book out that is
jam-packed with information if you are trying to make a living as a
corporate or independent content-provider for web or a print-based
graphic artist/designer (illustrators included).
It's from the Graphic Artists Guild and is the "Handbook of Pricing &
Ethical Guidelines, 11th edition". It will run you around $35.00, but
it's really priceless if you are just starting out, or even if you
have been in the business for a while.
You can find more information on the book, and the Guild, at
www.gag.org (no snickering from the back row, please).
