Dear Emaa:

Although of course it depends on the total word count of your thesis, $3200 sounds quite high. Did you ask them to edit it in a very short period of time? That can also significantly increase the total amount that a professional editing company will charge you.

I would definitely encourage you to look around a bit more since this is such an important investment in your work. A quick Google search will turn up plenty of potential editing companies. Thus far I have had several good experiences while working on my masters in education with www.admissionsticket.com One upside of their service is that they will provide you with a complimentary sample edit of your writing before you choose to use their service so that you can evaluate whether or not their editing work is up to your standards.

Again, I would encourage you to do some more research online and compare prices of several companies before making such a large investment. Best of luck in your path to publication!
