iOS + PHP ---- Upgrade an existing social dating app

Closed - This job posting has been filled and work has been completed.

Job Description

Please note:
1) you MUST understand both Chinese and English fluently. I will not review non-Chinese bidders applications.
2) This is a time sensitive task because we will need to submit the app to the App store on Dec 18th (we need to release it before the 2013 New Year). So you must be free to do a lot of work over the next 2 weeks.
3) You must be interested for a long-term commitment, because we have a lot of changes needed later.

I have an existing iOS app (Objective C) that's in Chinese. The previous developer could not continue so I need a new developer to upgrade the app. It is very similar to this application:

https://itunes.apple.com/cn/app/mo-mo/id448165862?mt=8

Which allows online dating. Members are able to search based on location, and initiate conversations, add friends, etc...

The server end is written in PHP/MySQL. We will need upgrades in both the iOS app and the server. Right now we need these changes:

1) Translate the app into English (we will provide the translation)
2) Add push notification feature (right now the app does not have push notification when it sends messages to other members)
3) Add credit system --- right now all features are free, but we want to make some features only work when the member buys "credits" (through Apple In-App Purchase). For example, we want to have the woman to send pictures for free but men will pay 5 credits/photo
4) Add emoticon in messaging
5) Fix some existing bugs, clean up some code
6) Add facebook signing in

Also I need your help to provide a flow-through diagram for the xcode project, because the previous developer did not do so.

I will need a lot more upgrades to my app done later next year (eg. video messaging, video calling, etc..), but the above 6 items Must be done by Dec 18th. I am willing to pay a high rate for an experienced worker for long-term relationship.

In your bid, please let me know if you've had similar experience working with Push notification, In-app-purchase, and Facebook integration. Please state that you understand Chinese, and that you are confident you can make the above changes by Dec 18th. We can chat more in details and I'm able to have a skype call to quickly show the XCode project in more details if you need.
