I am looking for a professional editor. I am finishing my thesis and i am looking for someone who would be able to perfect my Spanish. One of the comments of my supervisor is that it is not good enough to be a submitted this way but i have re-read and re-written it so many times i don´t know what else I can change.
The problem is that my supervisor comes with a lot of corrections every time i send something in so i still have not final version. How long would someone need to be able to correct a work of max 80 pages (and how much would it cost me)
