Learning about sales will feel more productive and in your comfort zone but you should start by going out there and talking to customers. Get out of your comfort zone.
I'd start by going door-to-door so you can start gathering feedback from SMBs and get a sense of the true ICP. Once you've closed ~10 clients this way then you should consider using a sales engagement platform like Outreach, Hubspot or Salesloft which will automate the cold email to call. If it's a 1-call close type sale, then you can use something like https://www.mojosells.com/. You can buy lists from Zoominfo or otherwise.
That all said, any type of human-centered sales motion in North America will require a minimum annual contract value of $10,000/yr to scale up.
