Convert PDF to KDP Formats

My manuscript is finished and currently sits in a single PDF file. I now want it live on Amazon KDP as both a paperback and a Kindle e-book, but I’m unsure whether my KDP account is even active and I definitely need help with the interior formatting.

Here’s what I need from you:

• Reformat the existing PDF so it meets Kindle requirements (reflowable or fixed, whichever suits the content best) and provide a ready-to-upload EPUB/KPF file.
• Create a print-ready PDF for the paperback version, complete with correct trim size, margins, bleed and embedded fonts.
• Walk me through (or handle directly, if possible) the KDP upload steps, including metadata entry and test previews, so the book passes Amazon’s pre-publish checks on the first try.

Please rely on Kindle Create, InDesign, Vellum, or similar industry-standard tools—whatever delivers a clean, professional result. Once complete I want to be able to hit “Publish” knowing both editions will display perfectly on Kindle devices and in print.
