hi there
a once a week clean isnt the brilliant contract that you want, you clean the office say on a monday, and then they have five days use. the of cleanliness to dirtiness is a roller coaster.
if you illustrate the effect a two day clean and the diference it makes to how clean there offices will stay.
then the cost of the two day service is competitiive.
i always used to hike a one day price up, and then sell the two day

martin
