In this kind of situations, what I always suggest is: create a network, work on the ground. Use social netoworks and groups related to the territory you work on. Find the user basin you want to tap into, figure out what kind of other services do they use, and get in touch with them. That's a good piece of advice both for marketing and events. I developed a business in a similar field, health&fitness, but in order to be more precise I would need to know what are the other local small businesses in your netowrk.
