simple rf transmitter

new to the forum so forgive me if i step on any landmines.



i have a project in mind in which i want to control a 12 volt automotive relay with a wireless control. at this time it would be 3 simple on/off circuits. since i have a very limited background in electronics, much less rf circuits, i am trying to find modules or simple basic circuits in which i could accomplish this. what are some manufacturers or distributors of such items or could a guy with a little bit of schooling like me build it myself?
