I thought about your ideas. I've had several poor experiences with customers in the past, and as a result, I'm more than a bit cautious. I would normally allow you to pay full price when the terms of my contract are fulfilled, but, in light of your preposterous belief that I should work at a discount because you hired a cut-rate photographer once, I would prefer that you pay full price before I agree to shoot a single photo. If I'm really impressed with my own work from that day, I'd like to charge you more than full price after the shoot is over. Does that sound fair?
LOL! Love this response!!
