geolocation push notification app for iphone/android

We need a web based admin panel that will allow for many different users to enter their addresses, and the radius distance around them they want to use to send app users push notifications if they get within the distance. This admin panel needs to communicate with the native iphone/android applications. We are going to have many different addresses and the native iphone/android apps need to send the push notification (different for each address and editable in the web based admin) whenever a user gets within a predefined distance (set ib the web based admin) We also need to set an upper limit of how many messages each user gets each day from the service in total. We need the a version for the iphone and the android. We will need all source code once compiled. It is perfectly acceptable to use simplegeo and urban airship apis in building this.
