iPhone App Developers

I need an App designed to work on iOS, Android, Blackberry Platforms. This is for a shopping mall. The app will contain, at the least, following sections: Mall Map, Retailer Listing by Category (Food, Department Store, Food, Entertainment, Banks, etc); Promotions, Dining, Stores, Amenities, Parking, Mall Info, Gift Cards, Popular; Leisure, Win, Wishes, Deals, Gift Ideas and a scan feature. Please note that icons are to be kept simple, and preferably in only 2/3 colours, but Im always open to new ideas. There will also be regular updates to the various categories. I need someone who can be creative, dynamic, works hard and fast and who is deadline driven. If you are that person, forward me your portfolio. The winning bid, will be offered the opportunity to form a co-op to grow within our local market and to be constantly available to make the changes required. I needs the app to be available on the following platforms: iOS, Android, Blackberry and Windows Mobile. Send your portfolio asap as I want to get this started soonest.
