Convert iPhone App to Blackberry App

We have an existing iPhone app that streams MP3 audio. We would like to convert it to Blackberry. You can download the iPhone app for free. Search "Calm Radio". The iPhone App has four "Free" streams and four "VIP" authentication streams. The Blackberry App will need eight "Free" and eight "VIP" streams. Authentication credentials are checked against a php script on our server. We have all relevant artwork needed. We will need to see examples of your existing and completed Blackberry apps.
