Cheapest idea would probably be one of the many FM transmitter kits available
and a discount store FM radio at the PA end. There are a lot of different
FM transmitter kits out there. Jaycar sell one, Oatley Electronics have
another one, and Wiltronics. Some are designed to take input directly
from a microphone rather than an audio imput, the audio input ones probably
do better quality audio.

Another option (and potentially cheaper/free if you have a lot of computer
junk like me) would be to use an old PC and a couple of WiFi cards. Set
up a local connection (Ad-Hoc Network) between the computer at the mic
end and the old one at the PA end, then use software to stream the audio
between them. Any PC/laptop post mid-90s should do the streaming OK, as
long as you don't choose something stupid in the settings. One of the
Raspberry Pi computers would also do the job, or a hacked router with
a USB sound card running OpenWrt, and I believe there are instructions
online detailing how to set either up to do the job (although they might
be a bit rough).

And there are audio receivers on Ebay for Bluetooth:

Some seem to say they can transmit the audio too, though of course the
PC with a bluetooth adapter could do that too.

ACTUALLY, scrap my initial sentence, these Ebay adapters would probably
be the cheapest option if they do what they say they do.

** 20m of cable costs very little.

This FM TX module works well, cost is US$6 or so, has an onboard mic
plus a line in socket and a USB port. I've got one that I run off a
single LiIon cell.
