I am looking to have an LED light blink when a certain vibration frequency is detected. I need a full prototype created and sent to me. This will involve an LED attached to a battery source and a IC that is programmed to trigger the LED when the frequency is detected. The frequency that needs to be detected is the vibration that comes from a "vibrate" ring from a cell phone. This device will be miniaturized to fit in a cell phone case so the batter source and IC needs to be small enough to be miniaturized.

The end product from this job must be a physical working prototype that will be sent to me along with specifications, parts list, and code for the IC.

Please only apply if you can do the complete prototype and understand that the LED can't blink unless only the frequency of that certain vibration is detected.
