A Book chapter Manuscript on US Occupation of Japan (9233 words including notes)

My book chapter manuscript is ready. It has been edited several times and what I need now is a highly experienced academic copyeditor to polish it and change endnote format to be a final product. Please read and understand the “Manuscript Preparation and Submission Guidelines,” “General House Style Sheet,” and “MN-Style-Sheet” first. This manuscript has 9443 words, but the first introduction part (written by the book editor: 210 words) needs no editing.
You will be asked to answer the following questions when submitting a proposal:
1. Are you a native speaker of English by birth? Have you ever worked for an academic publisher as a copyeditor (social sciences)?
