iPhone App for Google API data

Hello, We have a database (50-entry sample) of unique businesses (business name, address, phone). We require you to access Google's API database and match it with our database of unique businesses. Then create an app, that is essentially a MAP with NOTIFICATIONS. - The end result will be an iPhone application that displays only our unique businesses that google recognizes. -In that, when we add more businesses to the database, it is added to the app. Conversely, when the business is deleted from GOOGLE's map, it will be deleted from our database. SPECS: - The app is geo-sensitive (GPS enabled) so it sends a notification to the user when he/she is approaching one of the "unique businesses" - U.S.A- based - The map should be very similar to google's map (standard, satellite, etc) however the "unique businesses" will have their own icon/pin - within a 5 mile radius - Pin should also provide the user with the "unique business's" name and address - User should be able to get directions to the "unique business'" address (driving, public transportation, and walking) NOTE: We require the source code of the end product.
