Should I give up?
bdfh42: Pretty good advice from "wheels" but ask another question.What have your potential customers got to do to get a benefit from your start-up? That could be adding to the inertia - mild interest will only turn into a sale when everyone else is doing it OR there are no barriers to entry. It may be that you can offer to solve your first customer's problems by doing the leg work, development work, managing process change (what have you) for them. For instance, most businesses plan IT development work 12 to 24 months ahead - with competition for resources.A pain yes - but others will follow soon enough if they see someone else getting an advantage.
