n8n Workflow for Automated Business Outreach System

I need an experienced n8n developer to build an automated email outreach workflow that processes business data from Google Sheets and manages multi-step email sequences via SendGrid.

Core Requirements:

Data Processing:

API Integrations: Connect to multiple third-party APIs for data enrichment and content generation (details shared with qualified candidates)
Email Automation: Send personalized emails via SendGrid with proper tracking (opens, clicks, responses)
Follow-Up Logic: Automated follow-up sequences based on recipient behavior (no response = next email after X days, up to defined limit)
Logging: Write all status updates back to Google Sheets for real-time tracking

Deliverables:

Fully functioning n8n workflow (.json export)
Documentation: setup instructions, environment variables, API key requirements
Testing: Successful test run with sample data proving end-to-end functionality

Timeline:
Start within 3-5 days, complete within 7-10 days total.
To Apply:

Share links to previous n8n workflows you've built (especially those involving API integrations and email automation)
Confirm you can start within 3-5 days
Provide estimated completion date
List your experience with: n8n, SendGrid, Google Sheets API, multi-step automation workflows

Budget: $50-150 USD (fixed price based on experience)
Note: Full technical specifications will be shared with selected candidate. This project requires someone comfortable working with multiple APIs and building robust error handling.
