Modifications to existing codeigniter project

Hello, I am needing changes made to an existing CodeIgniter application. Please view the document I have attached and give me an hourly and cost estimate for you or your team to complete these changes. I am looking to have work started on this with-in the next 2 days so priority will be given to those who are able to commit to this project within that time-frame. The project is built in CodeIgniter and uses a MySQL database. Obviously without seeing the code I do not expect your estimate to be 100% accurate but you should have enough to give me a rough idea. You will have access to a testing server that is already setup with the site via SFTP (not FTP) access as well as remote access to MySQL using a client such as Navicat or sqlyog. Please post any clarifications to the clarification board so that I am not repeating myself. Please DO NOT register on this site as it is live and your information will appear to our public users. The testing site will allow you to do as much registering as needed when it is setup for you. Thanks and best of luck.
