Need 433 MHz hardware and firmware recommendation

Hi,

  I'm starting a new project for a client that needs a 433 MHz transmitter and receiver.  The distance between the 2 communicating devices will be fixed at approximately 5 ft apart.  There will be potential obstructions of metal between the 2 devices.  The data to communicate is 1-way only, and is just the value of a switch (open or closed).

  Can you recommend hardware and firmware (including starting example code) that can handle this requirement?

  Is there an existing firmware protocol stack for something like this?  I need to understand the firmware effort required.

  Thanks...

Brian
