a pricing policy that I was given a couple of years ago for custom quilts was $15 per finished square foot. That includes cost of material, labor, quilting, etc. If customer provides the fabric, pattern, etc, you make it a little lower. If the quilting or piecing is really complex, you can price it a little higher. If you calculate your size of 80 X 80, that comes out to about 44.4 square feet multiplied by $15/sq ft that comes to about $666 for the whole thing. From that figure, you alter the price as you see fit. Hope that helps.
