n8n HubSpot Lead Workflow

I need a production-ready, multi-step workflow in n8n that connects to HubSpot through its REST API and manages our lead pipeline end-to-end. The flow should accept data via webhook, create or update the corresponding lead in HubSpot, then branch into follow-up actions while tracking each step for reliability.

Key expectations
• Robust error handling with retries and clear fallback paths so a single failure never breaks the chain.
• Lightweight monitoring—status logging inside n8n plus a simple notification (e.g., email or Slack) when something goes wrong.
• Clean, readable node structure with comments and node-level descriptions; anyone on my team must be able to open the workflow and understand what is happening within minutes.
• A short Loom walkthrough—or, if you prefer, a concise written guide—showing how to deploy, test, and maintain the workflow.

The main automation target is HubSpot lead management (creating new contacts, updating existing records, tagging, and moving them to the next lifecycle stage). If you have ideas for extending the flow later—say, tying in an email service or a payment gateway—mention them, but the first milestone stays focused on HubSpot.

I will supply a clear process map, API keys, and any account access you need.

When you submit your proposal, please include:
• One or two real n8n examples you have shipped in production (links, screenshots, or repo snippets are fine).
• Your estimated turnaround time.
• A single fixed price for the initial build and hand-off.

Seasoned n8n builders with bonus experience in Make.com or Zapier—and anyone comfortable sprinkling in a light AI enrichment step—will stand out. I’m eager to move quickly once I find the right fit.
