I've done that in the past...didn't know any better than to rely on the phone books...learned the hardway.
Phone book companies hired great sales people that show you graphs and tell you how many calls you will get.
But like I have said...it usually isn't the advertisers fault if an ad doesn't work.
Usually is a bad ad or misplaced ad.
This particular ad runs at about $1000.00 per montha and it the size of a dollar bill...little bigger.
That's the price they told me but I think I could have gotten them down a bit...moot point.
Here is the ad
I put it together quick because it was a surprise that they were giving it to me.
The last job I booked, the lady said she liked my ad the best...and no I didn't ask.
