They might be able to get around the janitor etc problem by hiring a janitorial service company to do it instead of a full time person. This would work for many positions including both bottom of the pay scale and top. E.g. at the top of the pay scale you could contract a consultant to do an in-depth performance/security profile and recommendation report instead of hiring an expert directly.
