How do I build trust and guarantee results for a cold lead to make them ready to buy?

You said you almost guarantee results; I guarantee results—I tell you you'll get X, Y, Z or risk mitigation. There's a difference between an emotional sales decision, where people feel they need to buy now, and an intellectual sales decision, which focuses on positive ROI. A guarantee addresses both: intellectually, it removes doubt about returns; emotionally, it feels like a no‑brainer. If you’re willing to guarantee your service—and refund if you don’t—there’s no reason not to move forward unless there’s another unresolved issue, you’re untrustworthy, or you haven’t built enough value. So, just offer a guarantee. Don’t pitch it as a demo; that makes you perform like a dancing monkey. Instead, frame it as one business owner to another: show them something cool you’ve built, like a lead extraction and enrichment system that worked for a seven‑figure business, and let them see it. That puts you on equal footing and feels like sharing something valuable rather than performing for approval.
