If you know IRC well enough to want to mandate it for your company, you can probably set the server up in an hour or three. You can then install https://thelounge.chat/ and have your employees log into that for browser and mobile apps vs. native IRC clients.

What money would it require? Any leftover PC from the last 15 years can run the server.
