Website Baker Automatic Installation Script

We require someone with knowledge of PHP to develop an automatic installation script for an online website builder based around the open source Website Baker software. Createngo, offers users the chance to build their own websites for free online using Website Baker and free hosting. Currently, accounts have to be manually created, however due to high demand this is no longer viable. We require a solution that will:- > Take information from the user, such as desired website address, username and password. > A "Distribution" file to be copied and renamed with the desired website name. > Relevent information to be placed into a configuration file and relevent MySql entries to be added to a database. As there is already an installation script, this could perhaps be used as a base, but it has to be modified to make it easy for the end user to create their own accounts. In addition, should someone attempt to make a duplicate account, such as choosing a website name that has already been taken, the system should ask them to choose another.
