The English-native speaker is needed for
checking for mistakes in the text and make corrections
if needed.

The problem is that I wrote an ebook and I think
there are some grammatical and other mistakes, because I´m not
an English-native speaker.

My English speaking friends say there are only tiny mistakes, so
you will need only 1 or 2 hours to check it and correct them and
also tell me if it´ll be better to write some chapters in another way...

So we should talk on how to improve some phrases etc.

I worked hard on this ebook and nobody saw it, that´s why
