For anyone who's booking calls in the local business niche, what are the main problems & solution they want (I think it's getting them more clients) but how do you pitch them about that in a way that works & what type of offer seems to work best for this niche

So I'm mainly targeting local businesses from (UK, US, Canada, Aus) and I'm struggling a little with finding the decision maker's emails & phone numbers. Which free tools & platforms work best to find not only their contact info but also these businesses in general. Because I feel like using Google map is fine to fin them but u get numbers & emails that aren't good for outreach How do y'all go about this? Pumped to know!!
