Article writing needed

I am looking for a writer who can write 20 high quality article on various niches. No lengthy and boring articles, ideal word length should be 400-450. This is a lower budget project, so if you are expensive, don't apply. If you can't deliver 10 articles per week, don't apply. I need you to write few sentences or small paragraph to assess your writing skill. Project details will be provided to bid winners. Thank you
