A Simple Shopping Cart System

We need a simple shopping cart system to add on a non-ecommerce enabled website. Products are listed on current html website already, and when a buy bottton is clicked on, a buyer would be redirected to the shopping cart page to select product number, size and color, etc. 1. Products are added in back office by merchants in advance. The related info includes item name, price, selection of product sizes, selection of product colors, calculation of total price of multiple products, etc. 2. The system should generate a link for each product, and the link will be attached to the buy button on the non-ecommerce enabled webstie. That's how the shopping cart and the html website connected. 3. Database can be either a text one or MySQL, but prefer a text based database for simple installation. 4. Support PayPal and [login to view URL] payment gateways. 5. Send an email to merchant about the new order and also save the order in system. It would be better if you have a ready to use shopping cart, or if you want to modify part of an open source system, like osCommerce. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
