Hmmmm the bulletin boards may be a good plan; I have never tried this but it would probably be less labor. I found a place that does full color door hangers for about 10 cents each if you buy 1000. I don't know if I'm allowed to list companies here.
Abraham: I was going to say, I don't think I would do anything for $15, unless it was a small front lawn and even then it would have to be practically down the street to be worth it. lol I'm afraid I would get a bunch of people that didn't want to pay the full price if I did that; and then spend lots of time doing estimates while getting very little work!
