If you get good at stamping, I've got several contacts near you that would gladly put you to work. You still going with flagstone. Sometimes you can rent stamps or buy them cheap on the net. I bought a Increte territory, expensive then, now I buy most of my stuff local.
You can also go over existing concrete slabs with a product called thincrete and stamp it, do a lot of bars, dealerships, ect. this way.
Cool stuff.
