Automated PrestaShop Creation

When someone signs up for a store they are directed through a process that allows them to name their store... order domain... select hosting plan... and when their hosting account is created... their prestashop is automatically created for them. I want it to work just like: <[login to view URL]> Except I want to offer two options: 1) Turnkey DIY (store instantly created but they have to load their own products) This is just like [login to view URL] 2) Dropship Store - (where the products are already pre-loaded) An automated pre-loaded prestashop is created. I also want a nice landing page like [login to view URL] where they can start the order process. I am not familiar with PrestaShop.. but I would like them to be able to change their PrestaShop theme.. I dont know if this feature is standard or not. I have a server with root access where I would like the stores hosted.
