Hiring: iPhone Application Developer

Dear Reader,

I am from Switzerland and intend to take a Flash Application and make an application for the iphone out of it.
It would include use of the accelerometers but no other sensors.
You will get the Flash application so all elements of control and functionality are clear. I only wish to alter some of the graphics.
I hope I could give you a moderate understanding of what I intend to complete. Please ask me if you need further information I did not include.
How much do you charge for the development of such an application ? How long does it take you ?
I am aware of the fact that these questions are hard to answer precisely but I am trying to get an idea where and for what price I can get this done.

Thank you very much in advance.
