Work required for beta site backend

Hi Everyone, I need some work done on a beta site i have.I need a user to log in and be able to enter login details for a supermarket they frequent. Not all supermarkets allow users to see what they have purchased so i need on the admin end to be able to enter what supermarkets users can use their logins with. If they enter a supermarket that is not supported i need it inserted into a db for future research and to be able to alert user they can use logins. If player does enter supermarket we support then all data will be retrieved and shown in tables graphs etc like [login to view URL] / cakehealth.com. I already have the site and backend setup, i just need it further developed. There is a fair bit of smaller work that isnt too difficult that i also need done, so if you want to know everything needed pm me for full details.
