I would like a circuit which can control all types of camera releases detailed on the website below:

I would need a circuit where if I apply 3.3v then the shutter is released.
!!!The tricky part is that my project has to be low cost, and without a relay. This means that using BJT transistor is difficult as sometimes the current flows one way and other times the other way. I would need to be able to produce this circuit in less than $5.
I am looking for someone who can make a circuit for me which can act fully like a switch using a few transistors or other cheap components. The switch has to be able to conduct and allow flow of charge (current) in both directions.
