Just sharing my experience with dissertation proofreading services. When I needed my dissertation proofread, the cost was a bit of a puzzle. It depends on things like how long your dissertation is, how much editing you want, and how quickly you need it. My dissertation was around 10,000 to 15,000 words, so I paid something like $100 to $900. If you want extra special editing or need it fast, the price might go higher. I checked with a few proofreading services to get the best deal. One thing to remember is that the quality of the service is just as important as the cost. I found it worth it in the end.
