Princess Auto actually has pre-made remote control units now that are meant for operating car doors and starters and stuff, but can be used for anything. They're about 30 bucks and have four channels, and a tiny key fob with four "firing buttons" and a sliding safety switch too! The only thing is the unit's a bit bulky, and requires as 12V power source just to power the remote relay box. You can then put any voltage through the relays you like up to 12V.

I just checked their website and I can't find it listed so you may want to check your local store for them. They're in the automotive electrical section.
