Add facebook,twitter and web account log in to existing iOS app

I require an iOS development team to create a log in screen (inc graphics) and all functions to allow a user to simply sign in using : 1. Facebook 2. Twitter 3. Web portal account Other functions needed on log in screen (based on web portal) are : - Create an account - forgot password Attached is a mockup of log in screen. Lastly within the app there is 2 buttons "Facebook" and "twitter" that need to have functions add to : - Post To Facebook - Post to twitter When the buttons are tapped it will post to facebook/twitter "This is a test from CF app" I will provide details for web portal / database access. All the web-services are RESTful with JSON type. Database Server (MySQL) PHP v5.3 IDE Netbeans (v7.3.1) Repeat work opportunity Delivery within 5 days. iOS 6 and 7 compatible code. iPhone build only
