I have a book of interviews that is 107,000 words.
The interviews have been transcribed, edited, proofread, and approved by each of the book participants. I did Ph.D. studies in the humanities, and consider myself a good editor. I personally edited the entire book, and each chapter has been proofread by several people.
I need help with copy editing to prepare for print. Specifically, we need a consistent style guide to be applied to the manuscript for things like commas, lists, etc. Grammar doesn't have to be perfect, because it is a book of interviews, but consistency in style is important.
We would like this done within a week, and to start immediately.
