Proofreading a Business Book of 47,500 words

I'm looking for a professional proofreader for a short business book on client feedback.

It's approximately 47,500 words and is to be published via Amazon at the end of October.

The main requirement is to:

- Check and correct spelling, punctuation and grammar
- Check for consistency, clarity and coherence and raise queries where there is ambiguity
- Identify and apply consistent styles (e.g. capitalisation, hyphenation, spellings, headings, lists, numbers)

There's a sample attached to give you a feel for the style and content.
