New electronic product development, Phase 1

I am developing a simple, go/no-go sensor that detects the presence of metal parts stored inside a vertically-oriented metal tube. I envision a two post photo-interruptor peering through a hole drilled through the tube. When the parts level inside the tube drops below the IR beam, an audible alarm will sound.

The tube is .375" OD, .315 ID. The operating environment is indoors, clean, dry, room temperature, and away from sunlight. The finished unit needs to be reliable - my customer's will not accept junk that does not work. However, this is a non-critical application.

I wish to hire you to study my requirements and make a recommendation on the electronic/electrical components necessary to build this sensor. I will require specs on the components you recommend, including physical dimensions, brand names, calculated battery life, etc. I have more info available, including a drawing. Thank you for considering this project.
