Hello Sir,
I am an iPhone developer. I have developed some of the good apps both for iPhone and iPad. As per your requirement, I have a good knowledge of coding and working on new environment XCode 4.2
Also, as you said, the app is done and you need to finish it with uploading to App store. That is fine.
So, I would love to work on your application.
Technology is not the problem for me, As I am good with XCode and Objective-C.
We can share our Skype contacts. "siddheshDev" is my skype name.
It will be nice to proceed with you. Take care.
Awaiting your positive response.
