30 400 words original articles

I am looking for someone to write quality articles based on a some keywords that I will provide. I have 10 different websites for which I would like 3 articles each, so you will not have to write 30 articles on the same subject. It won't be kind of monotonous, you will have something different to write about. I want the writer to come up with 30 original articles (will be checked using copyscape). Each article must be 400 or more with a unique title, ideally 420 words. I do not want articles only for SEO purpose. The articles much contain the keyword that is given but I want informational articles that human readers would enjoy reading. The keyword phrase should be included in title (if possible at the beginning), in the first sentence of article (if possible at the beginning), once in the last paragraph and body text at least once. The articles should also include the keyword variations. The goal is to create the relevant articles that the readers feel are informative that also do well in the search engines. All you provide should be original and publishable by me with no fear of infringing on someone's copyright. Articles that are borrowed, copied or compiled from other sources will not be accepted. No copy and paste material. Please send in a competitive bid. Happy Bidding!
