AI-Powered Business Operating System Development

I’m looking for an experienced AI Agent / Automation Developer to build an MVP for a cloud-based personal business operating system, primarily focused on Real Estate.

The system will include:

* Central CRM and management dashboard
* Real estate properties, owners, clients, leads and deals
* AI matching between property supply and buyer/tenant demand
* WhatsApp Business integration and automated lead handling
* AI follow-ups with human approval
* Google Calendar, tasks and dynamic scheduling
* Marketing, social media and content workflow
* Digital products and order management
* Finance, commissions and purchasing tracking
* Market analytics and reporting
* AI Executive Assistant for daily priorities and follow-ups

Preferred experience:
OpenAI API / AI Agents, n8n or Make, WhatsApp Business API, Notion/Airtable/CRM, Google Workspace APIs, databases and business process automation.

I am looking for someone who can design the architecture and build a working MVP — not just a chatbot.

Please share similar projects, recommended stack, estimated timeline, fixed-price estimate, and expected monthly running costs.
