Edit and Rearrange Single-Page Book PDF

I have a pdf file for a book all in one with double pages but I need to separate and edit as follows (although i believe i have incorporated the 3mm bleed)

Cover File All in the same File / Document.
As Singles - 5 PAGE PDF
Page 1 - Front cover page 2 - Inner front cover page 3 - inner back cover page 4 - back cover page 5 - spine
Or a spread - 2 PAGE PDF
Back cover - Spine - Front Cover - Page 1
Inner front - inner spine - inner back cover -
Page 2
Text pages for PUR, Wiro & Staple books All in singles pages with 3mm of bleed all around in the same PDF FILE.

I would need a b&w proof (watermarked is fine) just to check with the printers that it is correct for them to print
