David,
Just wait a year or two.
When you get nine new cleans in one day, you'll be groaning and wondering how you can fit all the extra work in.
I've got five new cleans, all medium to large sized properties, booked for the end of the month.
I'm not looking forward to the initial cleans; not at all; they haven't been done in two years and they're country-houses, so they'll be spiders galore; horse-flies too; maybe!
