Hello !
Just to re-confirm please. You already have the text and you want someone to:
The aim of the project: make the text authentic, check grammar, spelling, and vocabulary. Am I right?
I can do it for you very quickly, with authenticity ,error free spelling and grammar.
Don't worry about the time difference. I can give it to you within1-2 hrs.
But, for that you will have to trust me, Can you ?
With thanks and regards.
