Blackberry and Symbian Camera applications

I need a camera application that works on symbian s60 FP1&above and another application that works on blackberry OS 4.5+. You can bid for either both symbian and blackberry or just one of the platforms. The requirements are as below for symbian and blackberry. 1. The application has a UI with 2 buttons. a) START b) STOP. 2. If the user presses START, the camera is reserved, but not started. A toast message is displayed saying "Reserve succesful" and then the application goes into the background. The application must be a high priority application such that other applications cannot acquire the camera if it is reserved by our application. In case the camera cannot be reserved or if the application looses the camera resource, an sms must be sent to a predefined number. 3. If the user brings the application to foreground again and then presses STOP, the camera is released and the application is closed.
