A freelance designer. Good ones are very good. You pay for the build, you pay again for every change, and when they move on the site stops being maintained.
An agency. More capacity and a bigger invoice. Usually right for a company with a marketing budget and a brand to protect, rarely right for a business of three people.
A website builder. The tools are handed to you and the work is still there. The builder is not building anything; you are, on evenings and weekends.
An AI generator. Fast, and it produces a page. It does not produce a decision about what your business should say, which is the part that decides whether anyone calls.
