iphone app progamer needed

We are looking to hire someone to put together an iphone app. It has been layed the out in Flash (it consists of 3 screens that are linked) and we know exactly what we need. We want to hire someone to use these files as a comp and write the script put it all together. It has to do with a phone, so calls would need to initiate and end and it has to link with the existing contact book, etc. We need someone with knowledge of what Apple requires. We won't discuss more details until a NDA is signed.
