cost of new foundation

[Marc Dube]

looking at a house that is currently a "seasonal" home but is in a spectacular spot. My first thought was to put a foundation on in order to turn it into year round. The value would go up by at least 80k just due to the location. I could also Air bnb it for $250-350 a night. So how mucu would it cost to put a foundation on this home? It currently sits on post and beam.
