Codeigniter pro to extend some functions

BIDS OVER $5/HOUR WILL BE IGNORED. Looking for a well experienced CI developer to help me extend some functions. Currently our website has a very simple support ticket desk. We need to change its functionality on the front AND the back end like adding categories, ticket type, urgency, etc. Please place your bid per hour, since I am not sure how long we need, since there might be some more changes after this.
