Cheap On/Off Switch Solution From 50' Range?

I'm looking for a solution for a single-pole switch(similar to a home light-switch) that can be turned off from 50'. There will be line of site. The device to be turned on and off will be using about 8-9 Amps at 12 VDC. On the control side, I was thinking about a cheap HC12 setup to an N-channel enhanced MOSFET. Is there anything cheaper and simpler?

What about the on/off control at that range? IR or RF? Something out of the box would be ideal. Thoughts?

if it is line of sight then you can use IR, it can work for a maximum distance of 10m. If you need more distance then go for RF. with RF you can get a maximum distance of 100m.
