Could you please make this project guaranteed?

This project is now committed. I am going to select the best and most complete design for the book cover. Thank you everyone for your participation.

What is the size of the final book, and how many pages in total for the spine?

The size of the final book is 8x10 - there will be 40 pages total.

Exact spine calculator can be found here: https://www.createspace.com/Products/Book/CoverPDF.jsp
