Before you invest any more time or money in your self-publishing project, invest in this book. It will be the best investment you make! You'll learn how to perform many of the publishing tasks yourself, so you can hire outside help for only those tasks that you really can't (or don't want to) do on your own. You'll learn what a self-publishing guru really does, so you'll have a better appreciation of what your professional co-creators actually do before you hire them to do it.
The Self-Publishing Guru has helped many first-time self-publishers (and some more seasoned "pros") take their embryonic manuscripts all the way to Amazon and other publishing outlets in print and e-book formats. In this book he explains how he does it, and shares with you the "tricks of the trade" that he has discovered over many years working on many publishing projects.
While he can't tell you exactly what to write, and how to write it (that's your job), he can help you to produce and market a book / e-book combo that will actually make you money (one way or another).
