doing digital signals is NOT simple.

CD player digital audio is much different than anything... Most cd players
have analogue out. Only the expensive CD players have digital out (the
$500 ones).

An analogue transmitter will cost $25 - 35, but not a digital one. Also,
you can't buy a .5watt FM transmitter legally in the lower 48. Only
Alaskans and maybe Hawians can have transmitters up to 10w. All lower 48
people are limited to 50mw, or 1/4th mile coverage...

You're not going to find a radio with digital outputs for under $2,000.
Digital audio and digital data are 2 extremely different things that you
need to get straight

The cheepest you will ever find them for is $100 for a transciever. You
need 2 of those

I DON'T have an income and I do electronics... :\
You need to reasearch cost of digital data transcievers...
