I have 3 my own WordPress blogs, and developed 5 Wordpress plugins.
I will develop automatic WordPress installation script for you. It will be a fully Web based application, written in PHP and MySQL. Using custom control panel you will can upload CSV list of domains with FTP user name and password, admin@email, admin login name, blog title, etc, control the process of multiple WordPress instances installation.
What's the reason to select blog title and email randomly? Will you plan to process not full list?
Do you have lists of WP themes from which application should select theme for the installation?
Do you agree that WP installation will be replicated from one ethalon exemplar with changes needed parameters in configuration only?
Or you strongly prefer that every WP instance installed from scratch?
As further development (other stage) we can add the feature to install and configure selected plugins, make automatical backup and updates for that list of WP installations.
May be feature to select blog from the list and automatically login to it for some manual tasks will be useful too.
