Code Igniter Developer Needed

We have an ecommerce platform that is built in Code Igniter that we need help with developing this month. The core functions are in the platform from sign up to checkout, but we need to make some modifications to the system per client requests.

For this client we are building an ecommerce tool that is membership based. A user will be able to sign up, log in, browse products, and make direct requests with the system admin. There is no purchasing on this site at this time, just contact made with the admin.

Some tasks that we will need help with:

Social signup/login
Invite membership implementation
Product search, browsing and filtering
Social sharing
User dashboard for account activity/support requests

We will provide the developer/team with all HTML5/CSS3 designs that will also need to be added to the system.
