I have the certifications you require, and then some.
I am a Preferred Freelancer.
I have edited/proofread/ghostwritten novels, non-fiction books, technical documents, websites, self-help books, CVs, masters' theses, doctoral dissertations, letters of application to universities, medical schools, and graduate degree programs.
American English is my language and style.
I look forward to discussing your assignment in greater detail. It is certainly as important to me as it is to you.
Might there be any potential for ongoing assignments?
Is there a deadline?
My bid is not necessarily written in stone. I am certainly open to discussion.
I appreciate your thoughtful consideration of my interest.
I am in the Eastern United States Time Zone, in St. Joseph, Michigan.
