I need an ecommerce webpage (hosted on Godaddy) for selling a new product

I have developed a product recently. Actually, it is currently (4) products. I have an existing website hosted on Godaddy for my engineering business. I want to add a page to that site where people can go to learn about the products I have created as well as place orders and buy. I have added the domain to my hosting acct on Godaddy. Who can create a simple ecommerce site for me. I will provide you with all images and content.
I have the subdomain name and hosting in place already.
