Neighbor down here is an installer. His posts are the foundation under the addition we're currently doing. The machine is about the same size as a small Bobcat. It has a short boom and drills helical posts into the ground until reaching a gauged pressure. He welds on a bracket and you build from there.
Homer has very little permafrost. Petersville has lots. I would avoid metal posts for that reason.
