OK, this is what I do:
On Facebook, do a search for your town (and surrounding areas), and you will find that recently "Selling pages" have popped up all over - this is basically "Freeads" type pages where people list things they have for sale. Some of these pages have thousands of members, and everything that is posted here automatically appears on their "wall".
So every week or so, I post a before & after pic, and I tag all these pages in it, so it shows on that page - and on the page of everyone who likes the selling page. Then, every so often, I delete the tags, and redo them, so it shows on them again.
At the moment, I have 128 likes - I know about a dozen or so of those, others are all customers/potential customers.
If you want to see how I do it, my facebook is
