Design 9 Blank Book Mockup Templates

Requirements: Editable custom made blank book mockup templates (for Photoshop). I require 3 each (3 different styles) for the sizes below (I need 9 blank mockup templates in total). They should be similar to the pictures I have provided and show the inside of the book and front cover. The book templates have to be paperback (not hardback), and thickness should be for 120-page book (around 6-7mm). The front cover in all of the templates should have a fold line as seen in example pictures. The Photoshop documents sizes should be 970px x 600 px. And the background of the mockup templates should be editable for me (so I can change the backgrounds).

Sizes:

6” x 9” (3 in total)
7” x 10” (3 in total)
8.5” x 11” (3 in total)

[[9 in total]]

I will provide examples images of what I am looking for.

Thank you,
Amin
