Even though you might have the most brilliant book idea on the planet and figure you and I can make a fortune if I'll just write it for free, I do not work on spec. I am a professional who uses her writing skills and experience to help others bring their book to publication. Not until I consult with a new client and discuss the amount of work that will be necessary to write and complete the manuscript can I calculate the exact fee but here are some general figures: Copy editing a manuscript $50 an hour Content editing, rewriting $100 an hour Writing a full-length book $15,000 - $35,500 Adaptations and novelizations $20,000 - $30,000 Book proposal $6,000 Query letter $350 Consulting fee $100 an hour   In addition, the client pays for travel expenses and the professional transcription service I recommend. If I am hired to write your book, I waive the book proposal and query letter fees.
