Hello.
Could you please share with me your prepared wire frame to estimate price and time needed to complete the project. I'll be very glad to cooperate with you in this task.
As for me I'm very knowledgeable in CODEIGNITER 2.2 and 3.0, PHP, MYSQL, HTML, CSS, JAVASCRIPT, JQUERY, AJAX etc. All of these are part of my current specialization. I have completed some projects on freelancer.com and you can see feedbacks of my previous tasks on my page https://www.freelancer.com/u/sinapps.html.
All my previous jobs refer to bug fixing, redesigning, continuing of functionality enhancements and developing new features for websites. Seems it's almost the same as you expect for current job. Moreover description of the projects on my page can give you information to determine what I really can do with CodeIgniter. And you may be sure I can do a bit more.
Anyway at present I have both time and desire to help you improve your website. If you want to discuss anything related to my bid please feel free to do that.
Best Regards,
Sinapps
