Final proofreading for a computer science book (US/Global English)

I'm writing a book on the topic of computer science that is going to be self-published. The book contains about 40 000 words on 220 pages in the current format. It was edited by a professional English editor and a dozen reviewers. However, I made some minor changes to the text since when. Now the book is in the final stage and requires another professional pair of eyes before the actual printing. I prefer the American English style since the book is targeted to the readers across different countries. Thus, I'm searching for a native-speaking professional proofreader with experience in both academic and non-fiction writing. ***Please, apply only if you are a professional editor and native from [US, Canada, UK, Australia, New Zealand, Philippines]. The final version of the book is in **PDF format** and has to be annotated using the standard PDF functionality. _Please provide an example_ of your editing style and professional level using the PDF with example pages (annotate at least 4 pages, use yellow for notes/suggestion and red for errors) that is attached. In this task, I expect from you the usual proofreading activity: - Correct grammatical and spelling mistakes. - Check precisely for "the/a" usage. - Set commas according to the modern best practices. - Alarm/correction for language stylistic errors. **I expect that we will make 2-3 iterations (you annotate - I apply changes) on the whole book until the PDF becomes well-polished. The time-frame for the first iteration on the whole book with corrections is 4-5 days. The whole proofreading process I need to complete in less than ten days.
