I think the first port of call is to try the JayCar solution and see.
Open to any others though.
Thanks again,

Jaycar solenoid is OK (easier than fiddling with relay mechanicals) , but you still have to interface it to your intervalometer, and for this you need transistors.
The intervalometer is NOT design to drive such relay directly - it just provides short from 5V to ground, and resulting currents should not exceed 5mA.

Maybe you need relay driver with digital input - If I dig something, I will let you know.
