Integrated Store for Dolphin

Hello, I am looking for a store module that can be integrated into the dolphin database, that is only controlled by the administrator. I want my users to be able to purchase goods through the store, browse the site, and have full functionality of dolphins interactive features, but not have to use a separate login for the store. The shopping cart should be displayed in their account functions and the account page, with previous orders, tracking, coupon redeem, etc... administration controls. I also would like the option to place a featured/popular/special products feed box on the home page with a add to cart now button that links directly to the product description page. Basically just like any other shopping cart, but integrated with the dolphin interactive functionality. Users should be able to post comments about a particular product, refer it to a friend, add to cart or wish list, and then when they are ready to checkout their information such as name, billing/shipping address, e-mail, etc... is queried from their profile. Then it will then be transferred out to payment processing (i.e. paypal, payflow, etc..). Please contact me if interested in developing this module or if you already have a module created with this functionality. I need this to be completed asap. Please make a bid if it's reasonable, I am ready to move forward immediately.
Thanks,
Jordan
