Copy Wiriting for an IT Company

I need 43 page content, 2 PR and 5 Blog entry for an IT company (total of 50 writings) All has to be unique, search engine optimized (I give you keywords for most of them) and has quality content. Of course they need some technical writing skills. Keyword density must be acceptable for SEO. I expect them to be around 500 words (PRs could be little less) Professional writing skill is a must! No use of "I", "we", "they", "this company" or some amateur references. They gotta be easy to read and sentences neither loooong or too short (One paragraph, 4-line sentences with lots of conjunction words are not acceptable!) Some services (for page content): Web Design & Development, Corporate Consulting, SEO, Social Media Marketing, Email Marketing, Application Development, CMS, Ecommerce Systems..
