Start with a brief description of your idea, being sure to mention why you wish to write the book, your budget, when you would like to begin and complete the writing, and whether you have already written anything or gathered research materials.In other words, give the ghostwriter enough information to understand the nature and scope of the project, then move on. Specifically, move on to finding out about the ghost’s background, experience, working style, expectations of you, cost, availability, and more.Remember that you are interviewing the ghostwriter to determine whether she or he has the skills, knowledge, interest, and time necessary to pen a great book for you.So don’t hog the conversation, talking only about you and your idea. Let the ghost talk. Listen carefully for the things that are unsaid that could determine whether you and this person have the “fit” that makes for a successful partnership.
