Amazon KDP Book Formatter Needed to Fix Existing InDesign File

My book is already professionally formatted in Adobe InDesign. I am not looking for a redesign. I need an experienced KDP formatter to correct the existing file so it passes the Amazon KDP Print Previewer while preserving the current design and comfortable paragraph spacing. The work needed includes: Correct all KDP margin/gutter errors without unnecessarily condensing the text. Preserve the book's existing typography, layout, and intentional white space. Restore comfortable and consistent paragraph spacing where it has become too condensed. Correct inconsistent/excessive spacing, including the large gap in the Final Reflection between “And most importantly… return.” and “Because that’s what changes everything.” Verify the Table of Contents against the actual chapter/section titles and page numbers. Verify pagination after all changes. Make sure no accidental blank pages are introduced. Deliver a final KDP-ready PDF and updated InDesign source file.
