Line editor for non-fiction book about film

I'm looking for an experienced line editor, or two or three editors working in parallel, to help polish my next book. It is a data-led non-fiction guide to how part of the film business works.

The first full draft is finished. The structure is settled, the research is done, and every figure and quotation has been checked against its source. The spelling is clean. Now it needs a good ear. I'd like the writing to:

* read more naturally, more like one person talking to the reader;
* lose any waffle, repetition or stiff phrasing;
* keep a consistent tone from chapter to chapter.

What the job is
* A line edit for style, flow and concision.
* Edits made in Track Changes in the Word files I send, with comments for anything you'd like me to decide.

What the job isn't
* Restructuring or developmental notes. The shape of the book is fixed.
* Fact-checking. Figures, dates and quotations must stay exactly as they are. If something looks wrong, please leave a comment.
* Proofreading for layout. That comes later.

Practical details
Length: about 150,000 words across 16 chapters, each standing on its own. Chapters range from about 5,000 to 25,000 words.
British English, with a short style sheet that I'll provide.
Who: I'm happy to work with one editor or to split the chapters between a few. If you can take the whole book, great. If you'd prefer a share, tell me how much.
Timing: I'd like to start straight away, with chapters returned as you finish them, so I can work alongside you.
Background: you don't need to know the film industry, but it would be a plus.

In your proposal, please tell me:

1. Your price, for the whole book or per 10,000 words. The price listed on this ad doesn't mean anything, as it's not linked to a certain amount of work. That's for you to suggest from your experience,

2. How long it would take you, and how many words you could do in the first week.

3. A line or two about similar work you've done.

4. I get a lot of bots auto-applying and people who don't read the brief, so please confirm you are a human in the first line of the reply. Without that, I won't read the rest as I'll assume you didn't get to this bit of the ad!

Thanks!
