Prestashop Module development

In Prestashop, i need to to develop a module which can be plug-in or plug-out without touch the code, what is the exact requirement 1. we have an application developed in flash( AS 3) 2. Application communicate with prestashop and get the product info from product table 3. after choosing the product when user submit it get the product id and by that product id it add that item into cart 4. we have to extend admin to upload different models photograph(a different section for models) and need to add an extra product image into the prestashop. these are the features we need to build up with a module so that we can just plug-in or plug-out that anytime. Please bid only if you have done this kind of module development before, its an urgent project so we need to this done this week so only bid if you can deliver into within 7 days. if you can develop the same with another cart systems then that will be an added advantage.
