I am an author that is working in the writing industry for 7 years. I wrote almost three successful books in this time. This year I am aiming to launch two books and for that, I am interested in taking assistance so as to produce more. This is the reason that I am looking for a ghostwriter who have the experience of writing amazing book content. However, I am unaware of hiring ghostwriters. Therefore, I need cost estimation that would require to hire a book writing expert.
