I get what you're doing and at the risk of taking the bait I want to point out that this is actually the way that a lot of WISPs that I know of operate. Build a network up to a certain number of customers that can be supported by 1-5 people and just leave it there and run it as a lifestyle business, or eventually sell it. I personally know maybe 10 or 12 people who are now doing or have done that in the past.

There are of course also businesses in this market that want to continue growing and I don't think there's anything wrong with that.
