According to Wikipedia, A ghostwriter is a person who is hired to author books, manuscripts, screenplays, speeches, articles, songs, blog posts, stories, reports, white papers, or other texts that are officially credited to another person.
I have done ghostwriting for blog posts, book reviews, resume, reports, matrimonial bio-data and web articles.
The charges depend upon the complexity of the project. Contact here for the proposal and quote.
