Supply, placement and hourly work are three things
These get used interchangeably and they are not the same. Manpower supply is the broad one: people deployed to your site for a role you define, across cleaning, portering, reception, events and general support. Housekeeping is the narrower cleaning placement, the same people on an ongoing contract. Hourly cleaning is ad hoc, booked by the hour with nobody assigned.
Which one you want is decided by the role and the duration, not by the headcount. A three-month project needing two porters is supply. A permanent lobby presence is a placement. A one-off event needing eight people for a weekend is supply again. We will say which fits rather than sell the largest of the three.
