Permies Forum Software Pricetag?

How much would the Permies Forum Software cost for someone to purchase who wanted to use it to set up their own forum?

I'm involved with a couple of groups that have a strong need for a proper forum platform, and this platform was my first thought. One's using a Facebook group, and the other a Slack channel.

I recognize I'm making some assumptions here;
- it's actually for sale,
- the software is actually portable;
- the software is one big monolithic thing, instead of a bunch of smaller interacting pieces
- the group is willing to pay a fair price to majorly improve something they're accustomed to getting for free
- And probably others I'm unaware of

But still, I'd like to pose the question, and see how possible this is.  Thanks!

Although we have made a bunch of changes.

Man, you're awesome, Paul.

I'll hop over there to try to solve my follow-up questions.
