Book on African History

I am looking for a skilled writer to help me create a book on Pre-colonial era African History. The book should primarily cover Sub-Saharan Africa and be geared towards a general readership. The ideal candidate should have a strong background in African history and be able to craft a compelling narrative that engages readers. The project will involve extensive research, writing, editing, and proofreading. The final product should be a well-researched, engaging, and informative book that educates readers about the rich history of Africa before the arrival of European colonizers. Experience in book writing and knowledge of publishing is a plus.
