n8n Expert for Content Automation System

Description:

I am looking for an n8n expert to build a complete and stable automation system.
I am familiar with n8n, the logic behind automations, and the Meta/WhatsApp APIs, but I do not have the time to set this up properly myself. I will understand your technical choices and can follow the workflow once delivered.

No issue if you use n8n AI (prompt-based workflow builder) to accelerate the build, as long as the result is clean, reliable, and editable afterwards.

Goal:

Allow multiple business owners (restaurants, salons, bakeries, etc.) to send their content via WhatsApp Business Cloud API, so that:

The system automatically identifies the client (Google Sheets)

Automatically creates and publishes posts on Instagram and Facebook via the Meta API

Each week, for premium clients, an AI reviews the week’s posts and sends personalized recommendations (WhatsApp + PDF/email report)

Tech Stack Required:

n8n (mandatory)

WhatsApp Business Cloud API

Meta API (Instagram + Facebook)

Google Sheets / Docs / Drive

Canva API (optional for auto-generated visuals)

AI (n8n-AI or OpenAI)

Deliverables:

Ready-to-use n8n workflow (exportable as .json)

Simple user documentation

Functional testing with 2 clients
