Have you considered finding a sales partner? Someone that already has the relationships with buyers in your target space? For example, educational book publishers? I always prefer to partner if I have technology that is useful to a niche market I don't have strong contacts in. They will be able to get to those who really have purchasing power and give you immediate feedback on whether there is really a market or not.
