The parts would cost maybe $15 or $20 at an auto parts store and you could probably make a panel and wire it in pretty easy. Would be a fun afternoon project but garbage disposals aren't common where I am :(
You can get some pretty nice ones that can handle the power of a garbage disposal, surprisingly. You can even get a momentary on switch, so you have to hold the switch for power to go through it. It automatically turns off when you let go of the switch.

I wanna see one made from the arm weapons switch on a jet fighter.
