I need to setup an online store about Mobile Phones and PCs, The website will allow me to create subscribers , each will have his own username and password to add his own items himself. this will need a massive data base that include all PCs parts brand, model, .. etc (i.e. storage devices, processors, RAM, ... etc) when the subscriber goes in to ad an item, the first pull down window will give the main category (i.e. storage device) , then the below pull down window will shows the categories (i.e. USB flash storage, HDD, External HDD, ... etc) then the brands (i.e. Segate , Western Digital, SAMSUNG, ... etc) , then he select the storage (320 GB, 500GB, 1TB, ... etc" . then finally he will enter the price of this item.
And I need to have my control panel that will allow me to create/manage subscribers (add, modify, delete, set max number of items to be added by the subscriber, add new line of business i.e. a new brand came to the market for the HDD called "X" ... etc) also to I need the website to be catchy and has some spaces on the main page for Ads.
Note: the bidder SHOULD have the data base for both the PCs items and Mobile Phones (brands and models)
