Most of the bloated, expensive sites I see are paying to maintain pages nobody reads. Start with these.
Home
The one page everyone lands on. It has to say what you do, where you do it, and how to reach you, all without endless scrolling. A visitor should know within a few seconds that they are in the right place and how to call you. That is the whole job. Everything else is detail.
Services
What you actually do, in plain terms, with enough detail that someone can tell whether you are the right fit. If you do a few distinct things, give each one room. This is also where a lot of your Google ranking comes from, because it is where the words people search for naturally live.
Service areas, if they fit
If you cover several suburbs, a page for each can rank for "your trade plus that suburb". This works, but only when each page says something true about the area. Ten copies with the suburb name swapped is a thin doorway Google ignores. If you have nothing real to say about a suburb yet, skip it. I cover the right way to do this in local SEO for tradies.
About
People hire people. A short, honest about page with a real photo and your story does more than a wall of corporate waffle ever will. For a sole operator especially, this is where trust gets built. Tell them who is turning up to the job.
Contact
Phone number, a simple form, and your service area. Make the number tappable on a phone and keep the form short. Every extra field you ask for loses you a few more enquiries, and I go deeper on that in getting more enquiries.
What you can skip for now
A blog you will never update, a gallery of stock photos, a team page for a team of one. None of these win you work, and an out-of-date page does quiet harm. Do the five that matter properly, and add more only when you have a real reason.
