Hello,
I'd be glad to edit your case studies for you. I am a native English speaking, professional proofreader and copy editor with more than 20 years' experience in a variety of disciplines, including medicine, law, technology and accounting.
I have also recently been selected to showcase my business and Freelancer experience on the Freelancer community page as a success story. Here is the link if you'd like to read the article:

We can mutually agree on a fee once the scope of work is determined.
Try me out - you won't be disappointed!
Regards,
Linda Shiffrin
