iPhone Application - Restaurants in Area with Geolocation

We would like you to develop an iPhone application: The menu screen will have 3 buttons: Button 1) Locate Gluten Free Restaurants This button will use GEOLOCATION to show a map of the users current location and shows certain restaurants on the map in the area. Button 2) Search for a Restaurant If they click here, there's a search bar where they can type the name of a restaurant. As they type, they should see the list of restaurants that match their search (this comes from database). If they click on the restaurant name, the user is taken to the restaurant URL (provided from database). The database is in this format: Name of Restaurant, Restaurant URL Button 3) Alphabetical Listing This will list all the restaurants in alphebetical order (taken from database). Please note: The list of restaurant names/URL's should be loaded off of MY SERVER DYNAMICALLY. So I can update the list of restaurants and it will automatically update on all the iPhone applications!
