PART 3 OF 4

A content engine that costs less than a Canva Pro subscription

n8n as orchestrator. Claude for copy. Lovart and Nano Banana for visuals. ElevenLabs for voice. The whole system produces 20-40 outputs per week across social channels and SEO landing pages.

THE ARCHITECTURE

How it fits together

Four stages. One orchestrator in the middle. Every stage swappable.

TRIGGER

  • Content brief
  • Calendar event
  • Manual trigger

ORCHESTRATOR

  • n8n workflow

Decides routing, sequences calls, validates output.

AI LAYER

  • Claude (copy)
  • Lovart (design)
  • Nano Banana (image)
  • ElevenLabs (voice)

OUTPUT

  • Facebook
  • Instagram
  • LinkedIn
  • Landing pages (SEO)

Capture and CRM flow into HighLevel, already in the stack.

THE TOOLS

Five tools, one workflow

n8n

US$ 0-20/month
What it does
Workflow orchestration. The central nervous system that calls every other tool, validates outputs, and dispatches to channels.
Why this one
Self-hosted on Elisa's existing VPS = zero recurring cost. Open-source. Cleaner than Make.com for technical workflows.

THE NUMBER

Total monthly cost

US$ 82-162/month

Depending on cloud vs self-hosted choices and output volume.

Hiring a junior content producer

US$ 2,500-4,000/month

Agency rates for equivalent output

US$ 5,000+/month

This engine

US$ 82-162/month

Where the team already pays for a tool, we route through it instead of adding a subscription — the goal is the lowest standing cost, not the most tools. I'll discuss implementation specifics live with the team.

THE FRAMING

What this engine is — and what it is not

This engine is

A force multiplier for an editor (me or Pedro or anyone else with judgment). It produces drafts, variations, options. Humans decide what ships.

This engine is not

A replacement for human judgment. The Sphere of Six brand has a careful voice — restrained, trust-anchored, anti-flashy. Every output runs through human review. The engine handles volume, formatting, and channel adaptation. People handle the editorial line.
