The chapter you’ve attached would require an entire rewrite to be comprehensible to an English-speaking (-reading) audience. While I’ve worked on numerous occasions with authors for whom English is not their primary language, usually I can make a pretty good stab at discerning what they’re discussing. I’m afraid that the chapter attached doesn’t lend itself to such easy interpretation. Working on this book would entail not only a complete rewrite, but likely much in the way of author/editor contact.
My bid for the editing would be $40 per manuscript page, and let’s define a standardized manuscript page as 265 words, which includes all notes and bibliographies. I would ask for eight weeks turnaround.
Proofreading would be done at an entirely separate stage -- after the book has been edited and formatted according to LN’s directions. Three dollars per page would be the rate there, but understand that it would involve no rewriting, but only reading for typographical errors.
Formatting: I would do that at the same time as the editing, at no additional charge.
Forty dollars per manuscript page. That’s roughly ten times my base rate for editing. And it still wouldn’t have been enough. Guaranteed.
