Codeigniter code development and modification

I am looking for a programmer to help with development and modification of existing CodeIgniter code. The project will involve enhancing the existing functionality, fixing existing bugs, and making cosmetics modifications to improve the user experience. I have existing source code available and am unsure if there will be a need to integrate any services. The ideal candidate should have experience working with CodeIgniter code development and modification and have a good understanding of code debugging and bug fixing.
