As long as customers choose services based on quality.

The HVAC for example - the large firms around you do not run HVAC/plumbing/electrical, they run marketing companies that happen to schedule and bill H+P+E service appointments.

That being said I've never heard or encountered a single services company in the US that can't find business, in fact it's the opposite. They're trying not to drown themselves in front of a fire hose.
