Update and Prepare Book for Publishing

am looking for an experienced book designer or publishing professional who can prepare updated print-ready files for Amazon KDP and IngramSpark.

The book is a picture book titled The First Fruits Festival of Kwanzaa (A Zulu Celebration). I have several revisions that need to be made to the existing files, including replacing the essays at the front of the book, adding a line of text to a specific interior page, adding a badge to the front cover, and adding quotes to the back cover.

The freelancer should have experience preparing and updating print-ready interior and cover files for both Amazon KDP and IngramSpark, including proper page dimensions, bleed, margins, resolution, color settings, fonts, and PDF specifications. I would prefer someone familiar with children's picture books and who can make the revisions while maintaining the existing design and layout.

The completed files should be ready for upload to both KDP and IngramSpark, with the appropriate files provided for each platform.
