Sorry for taking so long to reply. Great idea. We considered that, well I did, my wife (soon to be) was not gonna let that happen. I didn't even have to ask.
I did the cost analysis on doing it ourselves, it's gonna be pretty cheap. Now we'll have a nice guest cabin for people to stay in. It's not in the immediate vicinity of the home site, so it might turn out to be an off-grid AirB&B stream of income for the homestead. Thanks so much posting ideas , always gets me thinking.
