Feedback for my eBook Landing Page

Since the beta testers of the system described in the product(eBook) have given a very positive(100%) response, I thought it was time to release this to the public as a book.

The eBook has been designed beautifully unlike usual eBooks. This is one of the design feedback I got from the majority of the beta testers.

But, I am unsure how the landing page would perform. I decided to sell this to only around 250 people and I am thinking of using paid advertising.

I have a budget of around $500 per month for advertising with a total advertising budget of $1500.

So most visitors to my landing page would be from paid traffic. I am not sure if people would understand the content of the page.

It is a bit lengthy.

Any suggestions and feedback would be really helpful!
