Wireless switch , need help on how to make

OK , I am a tattoo artist. I want to make a wireless foot pedal to control my tattoo gun. This is how it works now. It has a foot pedal with a 1/4" phono mono jack that plugs into the power unit. When my foot is pressed down it simply closes the connection and tells the power unit to apply voltage to my gun which has a separate cord coming from the power unit. I would like to make a wireless for this. Maybe a simple remote control toy can give me all the conponets needed. I want it to be small , maybe a 9 volt battery supply. I can have my foot pedal  wire just 10" long going to the a sending unit with an antenna. Then alls it has to do is maybe close a relay that I can wire to a phono jack to just close the swicth to tell the power unit to turn on my tattoo gun. I know this is going to be very simple but for some reason im having trouble thinking of how to do this cheap. Thanks for the input. Jeff

I think about such wireless switching and the only solution I've been able to come up with involves wireless doorbells... Retro-engineer one and I believe it can be done!
