wireless light notification project

Hey guys,
I am new to playing with any of the transmitter and receiver technology so i decided to dive right in and try a simple project and I wanted to get some opinions on how I would go about this. First an explanation of my concept, I want to build a 4-Channel RF receiver that connects to four different blinking LED’s then have four separate transmitters connected to tilt switches. So when one of the switches tilts, the corresponding LED starts flashing.
so far I have started looking at the 2KM Long Range RF link kits w/ encoder and decoder as a starting point. what else besides the switches would I need to complete this project?

Thanks for the help!!
