Build AI chatbot on my website

I need an AI chatbot integrated into my website to respond to visitor inquiries automatically. The chatbot should understand natural language, handle common queries, escalate to human support when necessary, and maintain conversation context. Deliverables include chatbot setup, training with provided FAQs, web integration, customizable UI styling to match the site, basic analytics, and documentation. Experience with conversational AI frameworks, web integration, and UX optimization is preferred.
