Magento Ordering Customization

We have a shoe website that sells shoes by width and size. We have configurable products that contain all of the basic shoe information about each of the shoes we offer, and then simple products that contain every size and width combination. Right now consumers go to the product detail page and select size and then width. We are going to be creating a new customer group that will allow wholesalers to purchase through the website at wholesale pricing. We would like to allow them to order multiple sizes and widths on each product detail page through a grid with quantity dropdowns. This project include: 1) Creating a modification to the product detail page that shows all size and width ordering options when a specific customer group is logged in. 2) When the wholesale customer group customer is logged in, the standard ordering dropdowns should be replaced with a grid that includes all sizes and widths with a drop-down for each that is in stock, and an "x" if not in stock and an 'na' if not available (not every width is available in every size). The grid will need to use an additional product attribute called 'order' to determine the proper sequence for sizes since shoe sizes start over (ie. 9, 10, 11, 12, 1, 2). 3) The logged in user (from the wholesale customer group) should be able to select 'multiple' entries within the grid, see a 'total' pair of shoes they have currently selected on the page that is updated via javascript, and then press 'add to cart' with their entire order. 4) The shopping cart also needs to be modified to show only "1" cart line item per configurable product ordered, then also display the same pricing grid reflecting the quantities that were selected on the product detail page. 5) All front-end forms, tables, and containers should be assigned css classes so they can be modified from within CSS 6) Create an email template that shows the same grid by each configurable product ordered. We already have a design/header and footer; we just need the logic to paste in the order section including the grid layout for emails from wholesalers. IMPORTANT: * Please only bid if you have previous magento experience and can perform the job relatively quickly * See attached images for a basic example of our customer product detail page and how the wholesaler grid might appear * Must be willing to work on YOUR server and send files to us for testing * We can supply our theme if it is helpful * Coding needs to be compatible with Magento Version 1.7.0.2 * All coding should be clearly commented so that we can easily identify and modify as needed * Any scripting that can't live in the template itself, should be coded as an extension
