Have you tried posting flyers in local businesses that have bulletin boards? Leave business cards at the fabric stores and dress shops. I made refrigerator magnets out of business cards and give one to every new client. Some businesses didn't have a bulletin board so I made a small business card holder which they had on their counter with a supply of cards in it. Word of mouth is the most effective way though. It takes time to build your customer base. If I was looking for internet access I would try craigslist.
