As an English professional, I will be proofreading your paper to check for mistakes. This is quite a good service for the identification of typographical errors such as missing or repeated words, and other relatively infrequent punctuation errors that the earlier editing may have missed.
Note: I use the term "proofreading" loosely but my service is meant to fine-tune an already edited manuscript. For a more structural review, including sentence flow, narrative structure, and other general flow of the piece, I'd recommend my Copy Editing service for your purposes. Do take a read through my Copy Editing service page and portfolio for more information.
