I'm a professional writer based in India, and with an American education as well as publishing background. I have been freelancing for 10 years and have contributed to the likes of Times of India and magazines in the U.S. I'm also a published short story writer. My charge is approximate 10$ for a 300-350 word article. It might seem expensive but you won't have to worry about grammar, tone, and originality, and what you'll get is writing good enough to be published in any top magazine or newspaper in the country.
