My opinion is I don't think it is a good idea. I don't think it will get that much response. Also, how has yellowbook worked out for you? I used them last year and only got maybe 2 worthwhile calls and only one account out of it, and besides that they screwed up my ad and when I tried to get it resolved it was like a 4 month process. I personally after my experience canceled them and would never use them again.
