I need a serious content and line editor for an Islamic Book

It has taken a lifetime of research to write the book. It is based on serious research on the Quran. The objective of the book is to present Islam to the new generation. The author is a retired economist and university professor living in New York. The author expects the book to be seminal and original. At this stage the manuscript requires thorough content and line editing. The author is looking for a highly rated editor with solid experience. Knowledge of Islamic theology would be useful but not necessary. I am sending only 10 pages of a chapter at this time. The entire manuscript is over 80,000 words. Please do not waste your time and mine if you are not sure you can meet the high professional standard I am looking for.
