Employment works very differently in trades than e.g. software. The main thing is that customers don't care about the company they're using, but about the guy that comes out to help them. So picking up a clientele is extremely easy if you do a good job. And word of mouth multiplies that clientele pretty quickly. And the thing about the trades is that they always need to be done, endlessly. Paint starts to chip, electricity eventually breaks, plumbers go without saying, ...
This is why the normal trajectory, for a skilled tradesman, is apprenticeship -> experience -> accumulate clients -> go independent.
If you want to go independent in something like software you need, among other things, a good idea. If you want to go independent in the trades, all you need is a good reputation and enough people with your card. You don't even need to try either really. Do a good job and people themselves will proactively ask for your contact information. Finding a good and reliable tradesman is not easy.
