Objective C developer for ios with Web Services knowledge needed - repost

I have an ios application that works with the Instagram API's. I need someone to review our code and make the following changes. 1. I need the app to use a Client ID when logging in a user by pulling the Client ID from the Database. (currently it's hardcoded into the app) 2. The app needs to use a new Client ID for each new user when they login, by looping through the Client ID's in the DB. I'll have a series of Client ID's in the db, we'll rotate through them over and over again with each new user. 3. We have an IAP where users can upgrade to a Pro status, I want to disable Ads for anyone with Pro status. User credentials are stored in a DB. 4. Add the Flurry SDK to the App 5. New user registration is handled through an custom API/php file. New users are supposed to receive an initial Coin Count of 200 coins, some users are getting the 200 coins during registration, some are not.. need to trouble shoot why some users are not receiving the initial Coins. 6. Need to force users to have to relogin to the Application if they close the App on the device. 7. Change the api call to an SSL request (https:) 8. Need to verify Consumable and Non-Consumable purchases using In-App Purchase Receipt Validation. Automated bids will be ignored, please indicate in your message if you have experience with the Instagram API, PHP, Mysql and ofcourse Objective C. ** Please Note the following Milestone process ** The first milestone will be released after a working IPA is given for testing and considered working The second and final milestone will be released after the Source Code is given and the App has been submitted to iTunes Connect
