Format Three Spanish KDP Manuscripts

I have three Spanish-language personal-growth manuscripts ready for release and need them shaped precisely to Amazon KDP standards. All three titles revolve around mindfulness & meditation, goal setting & achievement, and emotional intelligence, and I want readers to be able to enjoy them in every format KDP offers—eBook (Kindle), paperback, and hardcover.

Here’s what I’m looking for:

• Interior layout files for each book that pass KDP’s automatic and manual checks the first time—EPUB for Kindle, plus print-ready PDFs for the paperback and hardcover editions.
• Cover designs sized for each trim, with correct bleed, spine width, and barcode placement.
• Consistent typography and styling so the reading experience feels seamless across devices and in print.
• An additional version of each book adapted for narration on my YouTube channel (clean text or a slide deck script is fine).

Acceptance criteria
• Zero upload errors or rejections from KDP.
• Printed proofs match digital layouts without shifts, widows, or orphans.

Let me know which tools you prefer—InDesign, Vellum, Affinity Publisher, or another professional solution—and share any similar Spanish KDP projects you’ve completed. Once we confirm milestones, I’m ready to hand over the manuscripts and move forward right away.
