Book reviewers in AUS/NZ/UK to proofread/review self help book

I need a few people who read books and are nice, or sometimes told they are "too nice" and are interested in reviewing my self help book on setting limits. Ideally you would have a (buyer) account on Amazon.

I am looking for people who can review my (short and sweet!) book and provide me with
- honest feedback/reviews on the book
- any errors or improvements to be made in your view

It's a workbook and I am not expecting you to have completed all the exercises/practices in the book (as that would take considerable time) - timeframe would be about 2-3 weeks, which will be plenty of time to review the book (under 100 pages).

You MUST be located in Australia, NZ or the UK and have a native like fluency in English. I would like to offer more money, but I can't - if you are in the "too nice" person category I believe you will benefit greatly from the book though, so you will essentially receive a free (digital) copy of it.
