E-Card Application for iPhone

We are looking for an application which runs on an iPhone, this application needs to access the camera-funtions and needs to have access to its picture-library. After taking or choosing a picture, a second screen shows a wordpad, where the user is able to type-in a limited number of characters, e.g. Greeting! The third screen has two options; A) to select an address from the inside address-book, or B) to typ-in a new address. We want to launch this application as two seperate products: -1- the user/client can dowbnload the app for free. With the unique code he has received, the user is able to add credits to the appliction, e.g. 10 credits. This gives him 10 e-card credits. Once the last credits is used, the application in only useable with a new code. -2- the user/client can dowbnload the app for free. The user adds credits to the application by purchasing credits thru the CreditCard, after authorisation of the CreditCard, the credits will be added to the application. The user now is able to use the full functionality. Both products as described, will send the data (picture, textblock and address) to our webserver. The iPhone will push out the data when he has access to a wireless network or other internet access. The data will not be sent by the mail-outbox! As long as there's no internet-access, the application will show the number of e-cards, waiting in the queu.
