Good books on the nuts and bolts of starting up
JustAGeek: "Growing a Business" by Paul Hawken - hands down one of the best books on starting a business I have read.
Don't let yourself be scared away by the release date 1988, the advice in there is timeless.
Lots of the author's advice can still be found in other books on that topic.
