Yes. Plenty of profitable trades run for years on word of mouth and a number on the side of a van. What you give up is narrower than people claim: jobs where somebody wanted to check you out late at night before calling, jobs where they asked for photos, and the price premium that comes from looking established.

What you do not give up is repeat customers, referrals, or contractor relationships. If most of your work arrives that way, a website will not change your year much.

The free fix that closes most of the gap is a Google Business Profile. It sits in the map results, holds your photos, collects reviews, lists your hours and service area, and has a call button. Most owners claim one and never finish it.
