I think this would be your biggest problem.
To transmit reasonable voice signal uncompressed would be tough.
Using compressed voice would bump up your cost

Scaling this back, for the moment, and assuming that I am successful at
getting a qualified person or team to take on the real work, let me ask
about the demo/presentation unit that I would have to build to make
that happen.

This would have much less in the way of constraints. No range issues.
No security issues.

I am currently planning on using a small off the shelf 418MHz AM 2
channel remote control. And then add a small TDA7000 or TDA7010T based
receiver with an LM386 as the amp. Plus a simple marquee flashing
circuit for the LED's. The transmitter for the remote controls would
be controlled by a USB relay controller from the PC.

Would anyone have any recommendations for off the shelf boards that
might combine some of this functionality into a smaller space?

Thanks for any recommendations,
Steve

First off, I would suggest looking at Zigbee and the various micros out there to support it. It would provide the power levels you need, the long battery life, and the ability to send encoded audio. It would also provide the security that you want. Even simpler would be to use an IR LED broadcast system, with the caveat that you need a lot more base stations...
