Customization of Joomla – VirtueMart Pizza online ordering

Customization of Joomla – VirtueMart to a VirtueMart pizza shop. Project description We want to create an online-food-ordering system with advanced capabilities as descriped in this document. The customer view(cart view) looks as follows: Online example is shown at: this is a link to our menus page... [login to view URL];Itemid=55 We need a way to add extras/toppings to an article. But not all extras are shown for every product e.g.: • Pizza extras are only shown for Pizza • Salad dressing/oil/… only shown for salads • Same applies to various articles (Pasta,…) The new price of the top article is re-calculated as the extras are added (without reloading the whole page). By clicking on the Extra ... Button a window (lightbox, shown below) appears where the possible extras are listed and can be added. Also the already added extras can be removed by clicking on them. WE need a site where the user can log in and the info like addresses are stored for repeted use... we need a deivery or pick up from store option and it would be nice if it could print out on one of the printers i my shop or talk directly with my pos (prism) An iphone app would besome iceing on he cake
