I don't know your exact location but if there are any livestock feed stores you get a lot of traffic there and people use those boards as a regular way of finding services.Ooooh I likey the idea! They might let me do that, they know me pretty well at the grocery store. There's also some ad boards at the two nearby Metra stations. Trying so hard to get all my ducks in a row before my first sit. Actually, before I meet with the client at the end of the month (to get the key and also have her sign some paperwork) I'd like to have it all set up.
There's someone on one of the CKD FB groups that I was talking to, she has a grooming business. She actually placed an advertisement via the movie theater (those ads that they show before the movie), and got a lot of business from that.
