Take it from someone who has pounded the pavement doing sales for my previous start-up, selling online lunch ordering service to restaurant owners, there is a lot of merit to what the parent's and grand parent's comments. You would be surprised how much many people despise technology. I think its because many of them were early adopters for various tech services sold to them by slick salesmen in the early days of software, and were then burned by how expensive and complicated it all was. They are now skeptical So yes you would need a stellar sales team, which I'm sure you will get. I love the idea by the way, and I do think there is a lot of scope. Best of luck!
