Hello,
I am a content writer and I have outstanding English grammar skills with quite impressive reading speed and a knack for spotting errors in written content. Since you want the proofreading to be completed within 10 days, I assure you that I would complete the task within 5 days, depending on the content, and won't give you a chance to complain.
Feel free to message me for further discussion.
Regards,
Ifra
