Article writing in different languages

We're looking for freelancers who are able to write a series of articles in: French, Italian, Portuguese (Brasil) and Polish. Articles should have the following characteristics: 1) A min. of 400 words 2) We provide keywords and the article should contain one keyword per article repeated once in the title and three times in the body text. 3) Articles must be original and unique. They can’t be a translation of articles written in another language. 4) Content should be neutral; our company shouldn’t be mentioned in the text. The subject of the articles can be decided by the author of the article: what counts is that the text contains the keyword indicated. For each language we need an amount of 25 articles per month. Contact us even if you are able to provide this service in just one of these languages. Please, take into consideration that this could be a continuative collaboration if we are satisfied with the quality and service you provide. I wait for your kind proposal.
