Code cleanup for codeigniter based system

I need someone with good knowledge of codeigniter to clean up the current code base for my system . The system currently works well but the code is not very clean and structured . It's a mixture of camel case standard and codeigniter coding style guidelines .The new code base must follow codeigniter coding standards. [login to view URL] This is pretty much a search replace job but you must have good knowledge of CI in order to test the functionality and make sure that it all works . These are the general guidelines : All code must follow CI standards ([login to view URL]) All database fields must follow similar formats too. E.g first_name instead of firstName The names of the views must follows similar naming conventions.
