online store project

Hi i want people to order my software online, and that the can use it direct. also i want to sell some additional products like a client pc. so people visit my website, and the order the software with additional products. On that moment, your script must create a new sub-domain for the client, setup a mysql database, and copy a package of files to the created sub-domain. what i don't want is a complete shop, i'm more looking for lets say a order page. so we need to find a way to but everything together maybe in steps or something.... like step 1, select software package , step select hardware, step 3 , other products, step 4 address step 5 payment but this is not it, the licenses must be connected to my software, so if a customer buys a second software licence, there client must be activated voor 2 licences. and all customers most have there own login with a personal page with all the bought products and [login to view URL] it must be multi [login to view URL] registertion info should be store in db you need to connect my software to the website i will create a demo for you so you can see what i mean you understand that every purchase needs a new sql database, subdomain, install php files etc? so people vissit my website, and the order my software with additonal products. On that moment, your script must create a new subdomain for the client, setup a mysql database, and copy a package of files to the created subdomain this must happen FOR EVERY NEW CUSTOMER over and over again. creating a subdomain is not a problem - what's archive/expiry date of subdomain? Payment systems integration paypal i am missing a reseller (partner program) its not the most important thing for now, but i need the preparation. i want dealers to login, so the can resel my products and get commision over the subscriptions. is the connection between the frontend and my software yes, for the subdomain creation, login, customer page with all info, i have a zip file, that includes, php files and a sql file. When i have a new customer, i create a subdomain example: [login to view URL] then i upoload the files, and create a new database inmysql. i run the setup, the setup uploads the sql to the database, and rights the connection settings to a [login to view URL] in the subdomain. I need to repeate this process for every new client. from the homepage users should be able to adjust the storage and there bandwith because thats where the pay for so you need to create a script that automates the process and clients should be able to login and adjust there settings, and buy extra subscriptions regards Ahmed
