"How much does a website cost?" is the wrong starting point. A $500 website and a $10,000 website can both fail to generate a single call. Price tells you almost nothing about what the site will actually do for your business.
The right question is: will this website bring in business? Is it built to rank on Google, convert visitors into calls, and keep performing over time — or is it just something to point people to when they ask if you have a website?
Those are completely different products. Both might be called "a website." Only one of them is actually an investment.
