Copy Editing / Proofreading for Ebook in English

I need a person fluent in English to review an eBook (approximately 80 thousand words).

Some details about the work:

This eBook will have some grammar and / or syntax errors, but nothing complicated or difficult to find, but it will need some copy editing.

The maximum I am willing to pay for this service is R$350 , however, if the freelancer delivers a satisfactory result, we have 4 more eBooks to be edited and these projects will be yours if you want them. Proposals above this amount will be automatically rejected.

From my own experience I understand that a week's deadline is more than enough to deliver the project, but keep in mind that quality is always more important than the deadline and if you need to spend more than a week to deliver a better job there will be no problem at all.

Send your proposal talking a little about yourself and your experiences, I need to know if you are a dedicated person and able to work in the long term as we will have many jobs throughout 2020.
