Copy Sales Farmer?

Build me a Marketing web app like Sales Farmer.

Sales Farmer does: Linkedin outreach automation: Sales-Farmer is a B2B SaaS that lets you build campaigns with personalized message sequences, and automates connection requests and follow-ups with configurable daily lim It reportedly makes about $304/mo, so the core idea clearly has demand — I want a lean version I can run and charge for.

Start from the open-source project langchain-ai/social-media-agent (https://github.com/langchain-ai/social-media-agent) — reuse what fits, strip its branding, and build the specifics below on top of it.

Requirements:
- Connect accounts (X, LinkedIn, Instagram, etc.) via OAuth; compose once, publish everywhere.
- Calendar + queue scheduling, drafts, and a per-platform preview.
- AI: generate post variations and a week of content from a topic.
- Basic analytics (reach/engagement) pulled per platform.

Also:
- Clean, modern, responsive UI with a thoughtful landing page.
- Email/password auth and a simple paid tier (Stripe test mode) so it's ready to charge.
- A README covering setup, environment variables, and how to deploy.

Ship a working MVP I can run locally first, then help me deploy it.
