Add Social Media Functionality to an iOS App--3

I have an app that is on app store, gets a lot of downloads and functions well but is missing some important social media elements. I‘m looking for someone to implement some UI changes and add some additional functionality. The app is written in objective C and calls data from a LAMP server. Some of the new functionality is data related so the ability to work in MySQL and PHP along with objective C is critical. Here are the changes required (I will provide a full requirements document after awarding the project): - minor change to registration page to capture different information (first and last name, specifically) - change flow of the app slightly (after login direct the user to My Page - a page that already exists) (this cuts out one page that will not longer be used.) - make some UI enhancements to My Page there are a few pages that are very similar in functionality - they are basically all the same chat format but in different contexts - game, team, my page and coach. they all need the same UI changes applied to them - add a navigation tab bar that includes a home button, “follow” button, search and a camera image to launch iOS camera (home, follow, search and camera functions already exist, this is a new way to access them. also, each has minor tweaks in functionality) - when a photo or video is taken (this function exists) I want to be able to add “who’s in this photo” and user location (app already captures user location but doesn’t apply it to audio/video. - “who’s in this photo” brings up a screen for selecting existing users or add new users. - capture and store Facebook, twitter, snapchat and instagram handles and store to user info - right now the app ties into Facebook and Twitter, I want to add Snapchat and Instagram. also, change the UI for selecting which social media to use - the app currently uses the camera for images and video, I want to change the camera interface so it’s just like the camera interface apple uses in messages - add a new screen that holds the roster
