Does anyone recommend a cold outreach tool?

I am planning on starting cold outreach to find an Automotive or B2B Services business in South Florida. For the past year or so, I have been running a self funded search with the help of a buy side advisor. It has been going well but the majority of my deal flow is either coming from my advisor (which is largely out of my hands) or BizBuySell (which is very hit or miss). My goal is to add another way of sourcing new deal flow that I can be in charge of, so I want to be able to see who owns businesses in my area. Let me know if you guys have any tools that you have used or any other advice you might have for me. Thank you!
