Please, I need help to design below circuit. I am not an electronic person by trade but I'm quite able to build a circuit if I have the required scheme and the details of components.

The functionality should be (see below drawing):
1. Switch S closing --> light bulb goes ON and stays ON for a set time. The time should be between 10min and 60min, manually adjustable.
2. After the above time elapses, with switch still closed, the light bulb should go OFF and stay OFF.
3. On set switch S to Open position the light bulb stays OFF
4. On close switch S the behaviour on step 1 should repeat and so on.

On light bulb Off I would like the power consumption for circuit to be minimal.
I need the electrical circuit and required electrical components.

Thank you!
