Create edit website backend using Codeigniter. PHP knowledge must.

I am looking for a Freelancer to create a website backend with Codeigniter and PHP knowledge is essential. I have the design already in place, and need someone to implement my specific requirements for Content Management. This will include user registration/management and content management. There will be no existing code to work with, so start up from scratch is needed. This project will have features such as data reporting and analytics.
