You have meaningful expertise with technology and, from the perspective of the average business owner, you know more about that then they'll hope to learn in a dozen lifetimes. As long as you can connect your expertise with technology to concrete business goals of theirs, you won't waste their time. Should they not be in a position to talk to you or work with you, they will not be shy about saying so. We business owners are in business to sell and be sold to. Money goes in and money goes out. This is what we do. You will not offend the typical business owner just by saying that you have an offering available.
It is entirely possible that your first forays will be flaming failures. Oh well! More fish in the sea. You'll at least have learned one approach that didn't work, or have heard concrete objections as to why they didn't move forward with you, as opposed to the illusory objections that devs think will cost them business, like "You do not have a Github" or "I don't think you've built a website for a homeless shelter recently."
