An online shopping site

My organization is a grocery store where we serve a wide variety of clients. Now we would want to open our frontiers to the coorporate world where we can serve dem whiles they are at work. I would want a site which is a one stop shop for all groceries and woul want the customer to just key the type of meal he/she would like to prepare. After taking this input the site gives a detailed recipe and then forwards to the customer the different varieties of prices they can choose from alongside its price.
