Scalable One-Page Local Business Sites

I’m building a service that equips neighbourhood cafés, restaurants, mechanics and other owner-operated shops with a fast, mobile-first single-page website. The aim is to start each prospect off with a free live demo, then convert them to paid clients once they see the value...
