Build an AI content pipeline on my VPS — n8n + Ghost with human-in-the-loop approval (Telegram)

My VPS is already set up (secured, Docker, and a Caddy reverse proxy with HTTPS running). Now I want the main thing: an AI-driven content pipeline with a human approval step, plus a self-hosted blog for it to publish to. I saw a working version of this and want my own that I can run and extend. What I need built: 1. Self-hosted Ghost blog, running in Docker behind my existing Caddy reverse proxy (HTTPS already handled). 2. Self-hosted n8n, also behind Caddy. 3. The core piece — an agentic content pipeline in n8n: - A webhook receives post content. - Creates a draft in Ghost via the Ghost Admin API. - Sends the draft to my Telegram with inline Approve / Reject buttons (human-in-the-loop). - Approve publishes the draft; Reject deletes it. Button state is handled cleanly. 4. A handover walkthrough plus a runbook so I can operate and extend it. What I'll provide: - VPS access (already has my admin user, Docker, and Caddy/HTTPS running). - My own Telegram bot token (created via BotFather); approvals go to my Telegram. Out of scope (may hire separately later): - SMTP / email / membership magic-links. - The upstream system that generates and sends content to the webhook (the webhook just needs to work when called, e.g. via a sample request). - Theme / CSS customization. Deliverables: - Ghost + n8n running behind Caddy on my VPS, each on its own hostname over HTTPS. - The full agentic pipeline working end-to-end, validated. - Written runbook and a live or recorded handover walkthrough. Acceptance: I POST sample content, a draft is created, it arrives in my Telegram with Approve/Reject, Approve publishes it (live on the Ghost blog), and Reject deletes the draft. Timeline: Within 7 days of giving access.
