WhatsApp Automation Transition from Twilio to n8n

I need my existing WhatsApp automation moved entirely off Twilio and Make and rebuilt in n8n while keeping the same user-facing behaviour. You will have full access to my current n8n instance and the Meta Business account so you can work directly on production-level resources... (Budget: $30 - $250 NZD, Jobs: AI Chatbot Development, API, API Integration, Automation, Chatbot Integration, n8n, PHP, Python, Software Architecture, Twilio)
