Articles to be re-written

I have 10 articles that have been written on a particluar niche. I need these articles to be re-written is such a way that search engines and visitors believe that they are unique content. Each article is based on a keyword and the keyword density needs to be maintained. The requirements for each article are; 1. The first paragraph must be changed completely. You can say the same thing but it must be re-written so as to be different and unique. An alternative to this is to add a completely new paragraph to the beginning of the article. 2. The last paragraph must be changed completely and consist of at least 4 sentences. If the existing paragraph is short then more content needs to be added. 3. You would need to add a complete unique paragraph in the middle of the article body consisting of at least 3 sentences. This paragraph must be relevant to the article. 4. Each article is to be reviewed for proper use of english, grammar and spelling. Some of the existing content does not make sense and this needs to be altered. 5. You must provide a new and unique title for each article and make sure that it contains the keyword. 6. I require 3 variations of the revised first paragraph, 3 variations of the revised closing paragraph and 3 variations of the revised body paragraph. The goal is to change the article by at least 40% so that it is considered unique content. I require a writer who has excellent command of the english language.
