I think every market varies depending on population, however lets face it there are about as many CC ads is there are attorney ads, in my market if you do it i think a full page or close to it must be the only way to go,I think it runs about $3500 a month for a full page. the first year I started my business I did a 1/4 page ad that cost me $750 a month, it was an utter failure, fortunately I set it up on a market expansion line, it generated exactly the calls they said it would however half where price shoppers the other half where solicitors I was only generating about $350 a month in revenue of it, so I canceled the ad early on. I do think if you have someone that is good handling the calls its a definite benefit.
we have several books the main one is qwest, which is the expensive one, the second is yellow book, along with a couple more that don't amount to much. I have a friend who does pest control and he loves the yellow pages says it works great for him. I think there is way less companies doing it in his market.
what I wanna know is how well YP's work for water damage, because one job could easily pay for a months worth of ad. its something I have had trouble tracking down. I do think one thing to remember is tons of people keep their old books, so the max draw for an ad will prolly not be seen until 2 or 3 years of your ad being in that book. go big or don't go at all, especially with CC.
