Another thing, is you can ask for help from your church. I mean, priests and pastors, for instance, know lots of different people and might be able to help you network, somehow. Maybe they have inexpensive ad space, as well. So, reach out and ask for some help. Another inexpensive marketing idea is to put fliers up at your local natural foods markets with your phone number (they always seem to have posting boards)...esp. if there are any in a wealthier neighborhood.
