Because your satisfaction is my first concern, I will work to the best of my ability to perfect your document in accordance with the level of editing you have chosen. However, clients are ultimately responsible for all content in documents they submit for a grade, approval, or acceptance. For this reason it is imperative that you review any and all editing I have performed and either approve or reject my changes; this can be done quickly and easily using the Track Changes feature of Microsoft Word. Because I may also insert my own questions and comments within brackets into the document, you must also be certain to remove any such additions before submitting your work. If you remain unsatisfied in any way, please let me know right away so that I can fix the problem at no extra charge.
Although I will do whatever I can to improve your document's chances of obtaining a better grade or acceptance by a committee, journal, or publisher, I necessarily can make no guarantees.
