I'm an expert editor and proofreader. I'd be glad to take a look at your document and improve it. When you say it needs more words - how long do you want the article to be? I can get it to you by 5pm your time if you get it to me by 3:45 pm your time.
While I am fairly new to Freelancer, I have years of experience in the field. I am currently the project coordinator at the University of Utah's medical library, where I create, edit, and evaluate a large variety of documents. My work is accurate, fast, professional, and I can start immediately. I am a native English speaker with exceptional skills.
