I have a lead for a large commercial job in sheep land.
Three buildings, all office and communal area carpets. It should take 3 - 4 days to complete and it needs done twice a year. There are also 200 office chairs to clean but not sure if those are a one off or also included in the yearly cleans.
I was offered it and also told to add on the cost of a travel lodge, but I don't do travel lodges!
