Conversion of iPhone app to Android app

We are an iPhone development company and would like to have one of our top iPhone apps converted to an Android app. The app is called Riff Raters. Users play their "riff" - a 20 second melodic phrase, directly into the iPhone. It is saved and other users can rate and comment on the riff. We have a top 25 section, a favorite riff, favorite riffer and the record section. There are web services required since the riff and information is stored on the web and downloaded to the phone. ## Deliverables We would like this done asap.
