I need help with an App Development ( iOS).

Hello,
I want to develop an app so I need someone that is wiling to work full time for at least 1-2 months.
I have a designer and I just need someone that will be able to write out the code or whatever is needed to get an app developed.

I want the app primarily for iOS.

I want the app to be very functional. I would like for someone with experience in app development.
