People respond to businesses like yours when they differentiate themselves. A social media campaign always seems like it is the easiest way to make something happen. It isn't. Take a look at your location. Are there a lot of businesses nearby? Women in those businesses can be targeted without resorting to the internet. See if you can get a poster put up in their break rooms. Offer a coupon. Make it easy to set an appointment. What about the men in those businesses. What about making "housecalls" in those offices for the executives?
