Write a sales page wording that converts for pre-ordering a book

Hi!
I am launching a book co-authored by a best-selling author Jeff Cox (The Goal) on Amazon KDP. The launch is planned for 15th March 2024. I am in the process of building a landing page that will be used for getting people to pre-order the book prior to its launch. I do have the script for the page, but it needs revamping to make it a killer page that converts ;)
The book is titled "Stand Back To Grow", which is an easy to read page-turning business novel. Its prime target market are overwhelmed business owners who have grown a business around them and in the process, have become slaves of their own businesses. It is a terrible and detrimental trap to be in and it feels impossible to escape. I have been there and found a way out, which paid off massively and now I am sharing this knowledge with others.
Attached is the first draft of the landing page's content that needs revamping in a salesy manner :) I have also attached a leaflet (still work in progress) prepared for pre-publishing advocates. It is not relevant to this project, but gives a feel for the branding colours, other messaging, etc.
