Theoretically, it’s possible, but it depends on the number of pages in your dissertation. Usually, it takes one person one hour to write one original page. That’s an industry standard used by most dissertation writing services. So if your dissertation is 20 pages, a writer can comfortably complete it in 2 days. However, if there are, say, 100 pages, a company may ask you to extend the deadline or decline to accept your order. Alternatively, it may assign several writers to work on your order. If you want to know which options are available, please contact the customer support of any legit company you like.
