The Graphic Artists' Guild pricing guide will help explain a lot, but generally, its pricing represents a national average which is higher than most regional markets. It's a great book, though. I usually estimate a round of simple revisions and include those costs in my initial pricing. However, revisions after that, or revisions to the design after concept approval are billed as extras. I try to let the client know, when possible, what the additional costs will be. Be sure you can handle the project, otherwise don't take it on. Charge as much as the market will bear, based on your experience, and the value of the project to the client. This business eats your life. Stuff almost always takes more time than you think it will, and clients drink blood and will strip the flesh from your bones if you let them. I'm very thin. --ratta
