The residential buyer is the source of much less repeat work, is harder to deal with, more price conscious and harder to collect from than the commercial buyer they could be working for.
Anyone that can competently market, manage, and execute that small job can do the same for better customers.
The crew that can build a driveway cannot build a parking lot, and they will never be able to break into that market because it requires experience that a driveway cannot give. From a parking lot there is then road building - the previous companies cannot break into them. Again there are just not enough projects of the size that sits in between to build experience.
Obviously much more than 2 weeks worth of work at a commercial job, since that's the worst possible kind of work you could ever offer any tradesman. Maybe 8x the hourly rate would be fair since it's intermittent work with generally horrible customers?
It's been interesting to watch the IT/engineering classes all of a sudden pretend to care about labor costs and outsourcing/job loss. As an industry they have been by far the most impactful in reducing wages, enabling outsourcing, and "gaining efficiency" via automation while as a class being paid top-tier wages for doing so. There is not another industry more directly culpable for blue collar job loss except perhaps finance and banking.
Only now when the shoe is on the other foot do such folks seem to care at all.
Learn to code indeed.
For any electricians/plumbers/etc. out there? Go get yours. When the shoe was on the other foot you were mocked and told to switch careers, lowballed on horrible residential projects, told to skill up and get better if you wanted to get paid more, there was no future in the trades, etc. Make hay while the sun shines and ignore the bleating. At least this time around the bubble is sharing a bit of that tech wealth.
