Recent technological advances have made it possible to generate accurate floor plans of existing properties relatively quickly and easily. These can then be posted along with the photos on Zillow. I am thinking of starting a business supplying such floor plans locally. Is there a market for this? I am considering pricing at 0.05 cents per square foot with a $100 minimum. Thus a house of up to 2000 sq ft would cost $100; 3000 sq ft would cost $150.
