7827 Custom shopping cart module

We use Joomla open source shopping cart with a component Virtuemart ([login to view URL] ). We sell flowers, and want add product customization capabilities. What is needed is a Virtuemart plug-in that will allow our customers to create custom made flower arrangement online with real time preview of the product they are creating. This new module will have the following features: Allow a visitor to Step 1: - select an image of a product ( bouquet, arrangement). This will be a background image which will preset only flower arrangement size and shape, and don`t have any flowers in it(there will be 4-5 different arrangement shapes/sizes ...these to be added in admin) Step 2 - select product from images already in the database ( these will be single flower images, and each of them has it`s own price and description) - visitor can select as many products (images) from existing library, and create custom made arrangement. Drag and drop the single product into the desired location on the background product image - ability to add more than one product at a time (say - if they need to add 12 roses, so they just select one rose and pick the number for desired items to be added) - new module automatically calculates the cost of the arrangement visitor created and when customer is ready they can add created arrangement to their existing shopping cart. - detailed description for this custom made product ( contents and pricing) automatically displayed in shopping cart. - created product image saved and attached to the order, so admin can see it from admin panel) The final product will be a Virtuemart plug-in. It can be done with Flash technology or GD Library or any other alternative solution .
