5 articles needed for translation company + submission

We need five articles (500~1000 words) for a translation company, which should then be submitted to article directories (such as ezines or articleslash). The articles will include specific keywords which we will give to the selected writer. Articles should be unique, we do not want a copy of a previous one. The articles posted on the article directories sites should include links back to our site, with the keywords in the anchor text, either within the article content or the signature/author profile. We need the articles to be posted and available online by August 30th. Our maximum budget is USD50
