Exactly, there really isn't much to it, but not everyone is as technicaly inclined as the average HN reader. You would think most restaurants would just do it themselves but my experience is that many of them don't want the hassle. It does involve in person cold calling but the researching of potential customers is easy(new restaurants without websites) and as far as not paying, I did run into that but it happened after the 1st year and all work and expenses for the first year are covered by the initial sale. I think it is more of a sales job and many people lack the confidence(or ego) for cold calling but I know it can create a significant passive income as lots of restaurants do keep paying year after year(especially if you are the domain name owner)
