Small Electronics Design

I am looking to have designed a small electronics system. The system will consist of a simple timer with user interface, a micro-controller, a light sensor, and a small speaker and LED light to serve as an alarm.

The electronics will be implemented into a small plastic and/or glass product. This product is to be used in the following manner:

-The user will enter a time (possibly hours and/or days), this timer will then count down. After the timer reaches 0, the speaker will sound a "beep" and a light will flash only after the light sensor detects a significant amount of light. The product will be kept in a dark place 99% of the time and will be in light after the user physically turns a light on. The idea is for the product to sound an alarm after the set time AND after the light sensor detects a significant amount of light.

At this stage, I am looking for this small electronics circuit to be designed for a prototype plastic/glass product. I am also looking for advice on how to implement this circuit into a plastic/glass product such that it will be able to be submerged in hot water and still function properly.

Any advice on manufacturing this circuit in large quantities (thousands of units) is also desired.

I have attached what I believe to be correct circuit logic for this circuit.

The light sensor is mandatory or not? Because the microcontroller can turn on the light and the speaker when the timer reach the "time up". Can you tell me what kind of the light and speakers do you want to you.
