Shooping cart for joomla site wanted - repost 2

I want to integrate a shopping cart into my joomla website. Below is a list with what I want to be done: - Create page where users can order products directly through buy now and the possibility of adding quantity . Add to cart button to be positioned after price .I want to be able to customize the minimum quantity for each product with a drop down menu(10, 20 , 30, 50 , 100, 150 or 25, 50 75 , etc. ) without the users have the option to add another amount such as 12 or 54 ). - Implement a rollover menu to site template for product categories - A date picker for when the customers will recieve the products . This must be displayed before finish checkout (eg the customer is placing the order monday and the products will be delivered starting Thursday ) . - payment method is cash on delivery, so no special requirements regarding payment. - user login menu on the front page - Guests to be able to see prices and add products to cart but for checkout they must register or login. - The site must be fully operable during the project integration An example how I want to look like is like in this link [login to view URL] My joomla site is available at [login to view URL] If you have any questions or proposals feel free to contact me.
