Hi, I need more info about your project. I'll be very transparent with you about my charges and I can only give you an accurate quote once I've seen the document. So please have a chat with me and I'll give you a fair and reasonable pricing. To give you an idea, I charge USD0.02/word for proofreading and correcting grammar, spelling, punctuation, and syntax. Speak soon.
Warmest Regards,
Pamela
