Non-Fiction Print + Ebook Design

I have a finished non-fiction manuscript that now needs a professional look in both print and digital formats. I want the interior laid out for a standard trim size ready for upload to KDP/IngramSpark, plus an EPUB (and, if you usually supply it, MOBI) that passes validation without errors. The cover should adapt smoothly between the paperback and the ebook versions while retaining a cohesive visual identity.

Please show examples of past book design work—especially projects where you handled both formats—so I can see how you solve typography, hierarchy, and imagery across platforms. If your portfolio already includes non-fiction titles, that’s a bonus.

Deliverables
• Print-ready PDF cover and interior, CMYK, with correct bleed and spine width
• Validated EPUB compatible with Kindle, Apple Books, and common readers
• Source files (InDesign or Affinity Publisher) so future updates remain straightforward

Once I approve the final proof, I’ll confirm everything renders cleanly on print proofs and major e-readers before releasing the last milestone.
