What kind of contractors do you need to build a home?

Find a general contractor.  He will know and get the other contractors/sub trades when they are required.

.   That is why I said telephone book. It is advertising they paid for to get their name out there.    Then again you "could go house to house and ask who built it(except for C 19 lockdowns)  People do not want to talk to strangers and you are a stranger to them.

Get a general contractor. They will hire sub-contractors for specific types of work, overseeing that the work gets done hopefully on schedule and hopefully properly.  You would have to be very experienced in house-building to use yourself as a general contractor.

You need a Building/Construction Contractor for the entire project.  This person will sub jobs out to the correct people; electrician, plumber, etc.

You need a qualified Builder, he will then sub contract electricians, plumbers, carpenters, tilers, roofers etc.

You can hire a general contractor who uses his own choice of sub contractors. Or, you could act as the general contractor and hire prolfessional LICENCED, BONDED AND INSURED contractors who specialize in their trade (plumber, electrician ... etc)

We hired someone to build our house so it looked finished from the outside (weather tight). We were left with basically a shell and hired independent contractors to insulate, do the plumbing, electrical and sheetrock/taping to come in and finish that part while we did all the painting and flooring, doors, trim wood work and finishing. 

Unless you know what you are doing, you hire a 'main' contractor and he engages everyone else. He is responsible for everything and you only have to chase one person and he provides all the access, waste management, welfare facilities and all the other things people forget about, for everyone else involved. Contractor means you need a proper contact. Be explicit about what you want so that he knows exactly what is required. If you leave any room for doubt he will interpret it the way it suits him and you won't have a leg to stand on.  Tender the job to at least three builders (and take up references or ask to see other work, you don't want a cowboy) and appoint him when you are ready to roll, making sure you have planning consents and building regs etc in place and there is nothing to hold him up. Once he is on board do not change your mind about anything or it will cost you.
