SEO ARTICLES WITH VARIATIONS

I have 5 articles to be written. These articles are basically SEO articles and each one of them requires 4 variations. Each article will have a 50 + words summary with a 400 + words body copy. This is an urgent requirement and I have tons of such requirements to be fulfilled. The payment per article (along with its 4 variations) is $ 3. I dont want you to be very creative. All I want from you is to have perfect English grammar and decent vocabulary. Please put up the quotes instantly because this is a super urgent requirement. Once this has been done, I have around 20-25 website articles to be worked upon. So, please note that the requirement is long lasting and continuous.
