Did a commercial today, price was £525.. but gave a good discount as I didn't think it would take that long. So they accepted on £400.. took 3.5 hours, easy work. Phoned the the lady who organised it, to tell her I had finished.
Her first words were, "Wow that was quick", so I was expecting some remarks about price and time.
She walked in and saw the first long corridor and immediately told me that they had been cleaned before but had never come up anywhere near as good. She was thrilled and paid in cash on the spot.
I asked her who had cleaned for them before. She mentioned a local cleaner, who I knew. I said to her that he is really cheap, she agreed, but added, he may be cheaper but it's worth paying the extra to have it done properly.
