Good luck with those power requirements. Wi-Fi is not cheap in terms of
electricity, especially if you want the normal coverage. There is a
reason Nintendo devices are 1mbps with tiny ranges.
You can probably do battery backup, trickle-charged to keep them fresh,
but going completely mains-free will be a design challenge. You will
have to pick your hardware very carefully, and manage the services even
more carefully.

You should be sending data over an SSH tunnel, anyway. Wi-Fi security
is a bad joke.

If you designed these right and then contracted a third-party to
construct hundreds of them, then you /might/ get the cost down to 100
units of your local currency.
Check out "Soekris" and similar offerings. Some people are finding ways
of setting up embedded or diskless OBSD edge boxes.
