I've actually read that book, it was a great read and loved the writing style. I helped me move away from hourly to fixed pricing but I don't believe I'm ready to bill on value just yet. I think I need some more solid projects behind me first and more experience before I make the jump.
FreshBooks has a nice little [free ebook]((https://www.freshbooks.com/blog/breakingthetimebarrier/)) about pricing too.
