Copyediting for book chapters x 4 (Chapters W, X, Y & Z)

I have written a business analysis book and need copy editing service for 4 chapters. Just so that you know the word count for copy editing work in each chapter contains;
Chapter W is 1700 words.
Chapter X is 1600 words.
Chapter Y is 1500 words.
Chapter Z is 1300 words.

Also i need someone to add chapter highlights at the end of each chapter (few bullet points, approx 80 - 120 words at the end of each chapter).
