Alarm iPhone App

The app I would like built is essentially an alarm type app. The alarm is triggered when a certain button on the page is pressed. The main page of the app will contain a button at the top. When this button is pressed the front facing camera will instantaneously take a picture. Then an alarm sound effect shall sound and the picture that was taken with the camera should flash alternately with another image. Whilst these images are flashing there should be a button that when pressed asks the user for a passcode to deactivate the alarm. When it has been deactivated with the correct code the user is taken to a screen with a message and the photo that was taken. The user should have the option of posting the picture and customisable preset message to facebook. The user should be able to calibrate the app via a settings page. They should be able to select: Whether or not a sound plays when the alarm is activated. Choose from a couple of different alarm sound effects. Set the period of time the alarm should play for. Whether a photo is to be taken or not. Set a passcode for deactivating the alarm. Enter their facebook login details. Button to start the app. I can give further details on request. Please let me know if you think you can build this for me, your price and an estimate of how long you think it will take.
