BlackBerry 10 (native) app - simple rules / alerts based on location

Hello - I need a simple BlackBerry 10 app developed (C++ or QML / Cascades will do fine). The app will allow user to enter "location" based or "time" based rules. For eg: User can click "new location based rule" : a) enter location: detect my current location b) enter radius (50m, 100m, 150m, 250m,300m) c) select an action: - mute my ringer - increase ringer volume - decrease phone ringer volume - sound alarm / play some alarm sound Similarly, user will be able to add " time based rules: Time based rule: a) enter start time: b) enter end time (optional) : c) enter an action to run: - increase ringer volume - decrease ringer volume - change phone profile to "normal" "phone calls only" "silent" "vibrate" etc. - sound an alarm d) incase of conflict with "location based rule" - which rule wins? ()location based or () time-based? This app is useful if you want to do certain things at certain times. For eg: - maybe you take a long bus ride and fall asleep on the bus? So, you can setup a location-based-rule to sound an alarm so that you wake-up on-time for your bus-stop. - maybe you want your phone to automatically decrease phone-ringer volume when you are in the office, and increase volume when you leave office. - maybe you want to set multiple alarms? So you can setup alarms using "time based rules". ---------------- Note: this must be a native BlackBerry 10 application. Must run on Z10 and Q10. Note: I will also need help and directions on how to publish this app to BlackBerry World. You'd have to provide me some guidance. If you have already created/published apps for BlackBerry, then this will be considered a PLUS! --------------
