Free-Plan Notion-HubSpot Sync

I want every new lead that I add to my Notion database to appear as a contact in HubSpot—automatically, reliably, and without paying for any premium tiers. The core objective is simple data sync between the two platforms, yet with two key requirements: every piece of full contact information (name, email, phone, company, notes, etc.) must make the jump, and the automation should first check HubSpot to be sure the person does not already exist before creating the record.

Because I’m on the free plans of Notion, Zapier, and Make, your workflow has to stay within their no-cost limits. Once the automation is running, I need a clear, step-by-step walkthrough—screenshots or loom video are fine—so I can tweak field mappings or troubleshoot on my own later.

When you reply, please include:
• Your fixed price and fastest realistic turnaround
• Whether you recommend Zapier or Make for this use-case (and why)
• A quick example of a similar no-code integration you’ve built for another client

If you can deliver a lean, cost-optimized solution and teach me how it works, let’s start right away—this is an urgent job.
