CodeIgnitor Developer

I need someone who is experienced with Codeignitor to build a simple application with backend that allows an admin to create dynamic drop down menus for users to select options based on admin defined variables. For example... admin can create categories and groups of dropdowns associated with each category respectively i.e. Parent Category 1: Dogs GROUP 1: Hair Colors a. black b. brown c. gray d. white GROUP 2: Breed a. pitbull b. poodle c. hound d. pincher GROUP 3: Food a. meat b. dog food c. birds d. turkey Parent Category 2: Cats...group1, group2, group3 Parent Category 3: Birds...group1, group2, group3 On the front-end... the user would select a category i.e. "Dogs" and we populate the page with corresponding dropdowns using AJAX. If user selects category "cats" then we display different groups of drop downs User can also delete drop downs and or add custom drop downs by inputting parent name, [name 1], [name 2], [name3] All the data is saved and stored in db. Let me know how quickly you can build this feature and feel free to give me fixed price also. I need speed and efficiency. I'm ready to start now.
