English Content Writer

I am looking for an English content writer to write 5 articles, each with 600 words in a specific field that will be told to the chosen writer. The source information for the articles can be found on the net easily. The 5 articles are only for testing purposes, if quality and price are good, we will buy 50 more articles in the very near future. Writer must have English as native language. Writer must be able to add the content into the CMS by himself (Wordpress or other CMS). Writer agree not to refer to this job in the future. Writer agree not to link to the site[s] and or articles from any website/page.
