To hire a ghostwriter or developmental editor who is right for your nonfiction book that incorporates your story and the lessons you have learned in your life, know the difference between the two jobs and which professional is right for you. Ghostwriters and developmental editors conceptualize your book, will guide you on whether you need a ghostwriter, and will charge you money. They do not work merely on the promise of future earnings if they are professionals.
