Proofreading for Python Book

I'm seeking a professional proofreader for my 500-page book on Python, targeted towards beginners. The book, which contains 175,000 words, needs a thorough review focusing on grammar and spelling. Technical accuracy and overall readability are not the primary concern for this project, but a keen eye for detail will be invaluable. Please note that the proofreader does not need to check for any specific formatting styles or adhere to a particular style guide.
