Right. I think you're missing my point a little bit. To put it a little more clearly: if you're marketing and getting zero leads, then you're marketing at the wrong folks. If business owners outsource their websites to agencies, then they don't care about your service, ergo your premise of "many business owners would use it" is not a statement around which to build a business. In other words, business owners should not be your target audience -- agencies should be. So if I were in your shoes, I would go talk to some businesses that you think should use this site and ask them straight up if they would use it. And when they inevitably point you to their agency, you should go ask the same question to the agency. I would not spend more money on ads until you have real user feedback.
