Has anyone used local advertising to find target businesses, especially print?

I'm doing a geo-restricted search in South Florida and my dad suggested that I advertise in the Miami equivalent of Crain's Chicago Business (which is, as far as I know, the South Florida Business Journal). I thought it was an interesting idea: I've considered trade magazines, but the drawback is that trade magazines tend to cover larger geographies. Overall, non-digital advertising like print or radio actually seems like a good way to target the kinds of businesses searchers acquire: ROI may be better than digital and the owner of a business with a 30+ year operating history is more likely to read magazines or listen to radio (again, generalizing here).
