I'm looking for an experienced article writer to write a keyword-driven article, plus 4 variations to each sentence. The articles must be original, well-written, between 750-800 words in length. The article will be based around 3-4 main keyword phrases, and must also contain as many "secondary phrases" as possible (Keyword phrases and detailed instructions will be provided). The article must be written in “American” English with grammar and sentence structure consistent with that found in a professional journal or popular magazine. If English is not your native language, you must be 100% certain that you can provide this level of quality. Your writing must be clear, on-topic, in context, appropriate and make sense to the reader.
