iPhone Do Not Disturb app

Need an app that has almost the same functionality as an existing app called Call Bliss ([login to view URL]). I have plans to add functionality to the app to make it unique compared to Call Bliss. The app should include the same navigation-bar functionality, screens and features contained in Call Bliss. Some minor differences (removed screens/functionality) are defined in the below additional requirements: Navigation Bar Buttons (Screens): 1. Active - this screen/window can be empty with no functionality (I will add to it later) 2. Groups - same functionality as Call Bliss 3. Places - same functionality as Call Bliss 4. Settings - this screen/window can be empty with no functionality (I will add to it later) Storing of the application's various settings can be done either via a local sqlite database (preferred) or plist file. Milestones: 1. Delivery of app with the main navigation controller and the navigation bar buttons defined above, with the Groups functionality working (same as Call Bliss app). 2. Delivery of app with all previous functionality (from Milestone 1), and the Places functionality included and working (same as Call Bliss). 3. Delivery of app with all previous functionality (from Milestone 1 and 2), and all integrated functionality working between Groups and Places (same as Call Bliss app). 4. All reported bugs fixed and delivery of final working app including all source code. It is expected that the developer will conduct their own unit, functional and regression testing to verify the app is functional before delivery of the agreed-upon Milestones, and should be prepared to provide details of the testing conducted.
