SPANISH Experienced KDP Book Designer Needed to Review, Improve and Finalize My Book for Publication

I have a book that is already completed and written. The content is finished and the book is very close to publication. I am looking for an experienced book designer, formatter or editorial designer with Amazon KDP experience to help me give the book its final professional touch before publishing. I do NOT need writing, ghostwriting or content creation. The manuscript is already finished. What I need: • Review the overall design and visual presentation of the book. • Reposition illustrations and images where appropriate. • Improve chapter titles, headings and visual consistency. • Review typography, spacing, margins and layout. • Provide professional editorial and design recommendations. • Improve the reader experience through better formatting and presentation. • Prepare the final version for publication on Amazon KDP. I am looking for someone with a good eye for design who can advise me on how to make the book look more professional, attractive and polished. Spanish language as a a native language preffered. Thank you.
