Non-Fiction Book Proposal Editing

I'm seeking a skilled editor with experience in developing winning book proposals, to help me refine my non-fiction book proposal. The book is a hybrid memoir of 98,000 words. The subject is my 25 year quest to learn the fate of an Australian soldier or 'Digger' whose unfinished, blood-stained diary was offered for an exhibition on the Great War at Dudley, England in 1996.I was the curator of that exhibition. My quest was an epic journey, full of serendipitous twists and turns, that took me from England to the battlefields of France and on to the soldier's homeland of Australia. In the process I was forced to examine my own attitude towards warfare, sacrifice, heroism, love and loss. My book is a testament to the value of the mundane, everyday items in our life. Items that have no intrinsic value but are, at the same time, utterly priceless. In the case of the Digger’s diary, an item that would elevate its writer from total obscurity to veneration by the people of the country he fought to liberate.

The book proposal includes the overview, synopsis and market analysis.

Key Requirements:
- Content editing to enhance structure and flow

- Strong grasp of market trends and analysis
