Where are you from that have apprenticeship? I am from Switzerland and this is a common career choice with 16 to do 4 years and be a certified technicians.

But as others have mentioned in other comments: Working for a company taking a big cut to install cables at peoples home with all the weirdness (smelly place, not at home, unfriendly, wrong description/tool) is not for me. I would suggest going straight with the goal to create a company asap and build an empire.
