3 x AA battery holder box needed but custom made.

Hi there, I need some help in making a very basic unit, which consists of 3 x AA battery holder 4.5v, Toggle switch, L.E.D light, 1 meter cable with opposing crocodile clips + & - (red and Black)

this needs to be set in an White ABS Plastic waterproof box.

I need 50 units built once the design and sample box has been inspected. any upgrades are welcome like use of different on/off switch for example.
