Wordpress Blog Install & Post Automation Script(repost)

I need a PHP script that installs Wordpress blogs and posts content to them with the following specs: Features: 1) Install one or batch of Wordpress blogs from one interface (user supplies domain, cpanel user/pword, etc) 2) Add & store themes that can be applied to any or all of the blogs 3) Add & store widgets that can be applied to any or all of the blogs 4) Add & store plugins that can be applied to any or all of the blogs 5) Auto-update any or all of the blogs when new WP versions are released 6) Backup & restore any or all databases on a schedule 7) Ability to create, save, and apply blog "templates" which have all the settings saved for easy creation of a new similar blog 8) Update existing Wordpress blog installs if desired 9) Upload batch articles or text files as zip or folder and schedule posting to any or all blogs 1 file at a time on user choice schedule of either x hours between posts or random (random posts 1 per day at a random time each day) - user can choose which category to post to, and can create new categories from the interface 10) Ability to search for and add RSS/Atom feeds to any/all blogs 11) Ability to auto add keyword-based videos from YouTube (and Viddler if possible) to blog as thumbnails in sidebar widget (user supplies YouTUbe login info) Please see: [login to view URL] because I am basically looking for a clone of that script with some modifications. Please quote time to complete and cost--we can agree on a more specific project plan and finalize cost/time in more detail before we start... -Brett
