The Espresso website gives all the basic info on printing your self-published book on demand, but it seems you need to connect with the individual outlets for your cost. The UW offers all the pre-press services you need, but again, you’d need to connect with them about cost. At this point, it seems like a good option for obscure academic subjects, family vanity projects (cookbooks, history, memories), but not so much for someone trying to reach a mass market. It depends on your goals for your book.
