160 SEO Articles A Month + Miscellaneous Ad Hoc SEO Tasks

I need about 160 SEO articles of about 500 words each for 10 clients (16 articles per client), all on various topics. So topic versatility is a must. Topics can be easily researched online.

In addition to this, need ad hoc SEO tasks done (posting the written articles to blogs, directories, Web 2.0 sites, rank tracking & reporting, etc).
