Hi Emily,I’ve been reading a really great book, “The Designer’s Guide To Marketing And Pricing: How To Win Clients And What To Charge Them”, it’s a recently published book (I think in ’08) and I’ve found it very helpful in determining how much to charge clients for custom design services.This book has a few worksheet-type pages where you breakdown the costs associated with running your own business, including overhead, your salary, making a profit, etc. I’m completely new to the custom design/letterpress business, so having this as a guide is helpful. The thing that’s stressed in this book is not to charge an hourly rate, rather figure out how much time the project will take you and name your price, but it does help you figure out your hourly rate so you have it to figure out how much to charge!It’s also got information about contracts, marketing and whatnot that could prove to be helpful…the one thing I like about it too is you can pick and choose what you want to read about and jump right to that chapter and not be completely lost!Good luck!Kristinahttp://www.amazon.com/Designers-Guide-Marketing-Pricing-Clients/dp/1600610080/ref=sr_1_1?ie=UTF8&s=books&qid=1252691150&sr=8-1
