I live in a large upscale community, full of the types of clients I assume you are after if you do residential work. It's all about word of mouth and the mom network here. There are private Facebook pages just for our neihborhood that are focused on all demographics.....mom's of teens, mom's of tots, resident recommendations, etc.... Talk to your existing clients, see if they are members of such Facebook groups and ask them to recommend your service and share your page there.
