All that I am given to understand is that you need an article writer. Assuming that the article would be on a topic that did not need mentioning, (technical know-how), I would be concentrating on the language, the flow of the article and the lucidity of the content. The attempt would be to make it easy to comprehend.
In case it is an article requiring some research, I will make sure the research returns the most reliable results that can be used and incorporated well into the article.
For further clarification, I'd like you to give me more inputs or discuss your requirements more elaborately with me.
