The target market for cleaning services consists of property owners and renters. A great place to start to build your network for your cleaning company is with landlords. Landlords tend to have an extensive network of other homeowners and leaders within the real estate industry, so their endorsement will go a long way toward promoting your cleaning business. Make sure you’re targeting individual homeowners and renters as well, so you don’t give off the impression that you’re excluding your business from these profitable (and often loyal) customers.
