Fail on using 2 Transistor as a Switch
simulate this circuit &ndash; Schematic created using CircuitLab

This should do the trick.
I used the lightbulb as your load/output
and the switch(SW1) is now normal-closed
Q1 can also be a N-Channel Mosfet.

This should work like this:
SW1 is closed so Q1 is active and bring the gate of M1 to ground.
If SW1 is open Q1 is closed and the gate of M1 is on 12V

This is a low-cost-solution
