Format Canva Book Layout for Amazon KDP

I have already designed a book layout in Canva, but the font sizes, margins, and formatting need to be professionally adjusted for a 6×9 inch paperback print on Amazon KDP.

Current Status:
File is fully created in Canva
Font sizes are currently too small (~7.4 pt Open Sans)
Need guidance and implementation for ideal readability

What I Need:
Resize the document correctly for 6x9 inch trim size
Adjust all body fonts to at least 10–11 pt
Set proper line spacing (leading) and margins suitable for paperback
Ensure headings, footers, and page breaks are well placed
Deliver KDP, Notion Press - Ready PDF (print-quality resolution)
Ensure bleed/margin is adjusted if needed
Quick turnaround preferred (within 1–2 days)

Deliverables:
Resized & reformatted Canva file
Print-ready PDF file for Amazon KDP
Optional: 1 test printable PDF page for preview

Ideal Candidate:
Canva formatting expert (non-design heavy)
Experience with Amazon KDP standards
Detail-oriented with font/layout alignment
Can work fast and communicate clearly
