Vibrant Paperback Layout Formatting

I have a completed manuscript that I want reshaped into a short-read paperback. The work I need is strictly formatting and layout design; all text is final, so no editing or proofreading will be required.

The finished interior should feel colorful and vibrant, with bold, playful typography that keeps the eye moving while still reading cleanly in print. I’m picturing a design that uses lively accent hues for chapter openers, pull-quotes, or section dividers, balanced by generous white space so the pages never feel crowded.

Here is what I will provide:
• The manuscript in Word (approximately 18–20k words)
• The working Book Cover Front and Back to set the tone
• Any front- or back-matter text you need (acknowledgments, about the author, etc.)

What I need back from you:
• A print-ready PDF (bleed and crop marks included) optimized for Amazon KDP paperback
• The native working file (Adobe InDesign, Affinity Publisher, or similar) so I can update later if needed
• A separate PDF proof for quick on-screen review before final export

Please let me know which layout software you prefer, how many rounds of minor tweaks you include, and an estimated turnaround time. Once we agree on the specs, I’ll send the manuscript immediately so you can dive in.
