Hi,
I've been so critical to the course provider where I took my AWS courses, they asked me to become a freelance writer for their site
I'll use the same critical view to check your book.
My bid is based on no information, your description doesn't show the amount of words. I calculate $0,05 per word. So the amount may change with the actual word count.
To check the text properly, I need it in a file format from which I can easily copy/paste to translation tools (I use Poedit) so I can keep a clear overview of my work.
Best regards,
Erwin
