I have a chat app running in android and iOS. It is working very well in android but iOS is having problems. So i have to redo the chat portion of the iOS app. We are using Pubnub as the chatting platform, so if you have experience with pubnub then you move to the front of the line.
Please include the following in your proposal:
1. When can you get started?
2. How many chat apps have you made in iOS?
3. What technology have you used to implement chat?
