Facebook app

I would like to develop a gift-sending Facebook app. I will give you the complete psd template for all the pages and you should develop the app. The app will contain : -classic facebook buttons (like, subscribe, publish, add profile tab) -invite friends on app (can invite friends on app,) -level bonus (when sending a gift the user will receive points and get to the next level where special offers will be available) -gift shop ( can send virtual gifts/e-cards to any friend on facebook ) -small CMS for admin (add/edit/delete gifts, offers, auto messages, etc.) + (can add text & picture and post announcements and offers directly to users wall. ) -app permissions (access my friends information ex: - birthdays . All friends birthdays will be shown into a calendar inside the app / each user will be notified trough a post when a friend`s birthday is close. The app should be able to auto send special messages that have been added by the admin) I need only motivated experienced developers so please do not contact me without showing a portfolio with a relevant work.
