Hello,
I will rewrite / copy edit, and/or proofread the document to ensure that it flows well, has no grammatical errors, and is clear. When it comes to rewriting or editing, I will go through your work with a fine-tooth comb, making sure that the end result is free of errors, such as misspellings, incorrect punctuation, and poor grammar. As for rewriting, I will streamline your content in a way that lets readers understand exactly what you are trying to convey by improving sentence structure, word choice, and the flow of the text.
I'll send you the document in time.
