I don't think $9,000 is too much for what you described. of course my cleaning expertise is based on what I was doing in Australia, and New Zealand, but I targeted "high end" clients, and I made a point of pointing out the areas of the contract that needed lifting, as I was doing a walk around. I made a further point of saying that in no way would I be satisfied if my cleaning crew left the premises in the state they were currently being left in.
My most exclusive and valuable contract was a top end function center that catered to weddings, bah mitzvahs, anniversaries, etc. They would hold approximately 180 functions a year between the three function rooms, and after 300 people had been through the venue, it would take a crew of 3 people, 5 hours to clean from tip to toe. Then I would inspect the following morning. In the slower months the average number of services would have been 3 a week, and over the Summer (Christmas) period, that would increase to 6 services a week.
I also handled all security and maintenance for the venue, services which were added after I started to clean the place, and only when I explained how it would be far cheaper for the venue to contract all services to me, as opposed to having three companies handling various aspects of the center.
I am not sure of the size of the place now, but the contract (cleaning only) was returning $40 an hour, and I held the contract for almost 6 years, until I decided to sell it, and move back to New Zealand. Don't undersell yourself. Pick a market and stick with it, specializing in what that market expects.
