iPhone App - Need App Clone (VERY Basic App)

I need to have a clone made of a particular iPhone app, which is most similar to an anti-theft iPhone app that beeps and sounds an alarm when someone moves the phone. I want to make a similar app that performs these same functions. So the app will need to allow users to set either an alarm or a vibrating when the phone is picked up and someone attempts to use it. Please let me know how cheaply you can do this and what you can do to make this a quality application (will you be available for updates, can you do to the design of the app and take care of that?). Include the phrase "elephants love peanuts" in your response please so that I know you've read this entire paragraph, thank you!
