Create order page of http://www.eslor.com/

[login to view URL] is the web site made using Ruby on Rails and MySQL. The order page is currently inactive. We would like to create the order page in which has a shopping cart facility and the user when done checks out using [login to view URL] payment gateway. We would also like a general admin page to be created in which the user can change the images of the web site and do other admin tasks. Ruby on Rails should be used to do the above. We will provide the existing Ruby on Rails source code / relevant MySQL database and [login to view URL] credentials.
