Website Customer Support Chatbot Development

I need a conversational agent that lives on my website and can field customer-support questions in real time. Its main job is twofold: give visitors clear, accurate product information and walk them through basic technical troubleshooting before any ticket reaches my human team.

Here’s what I expect:
• A chatbot built with a framework such as Dialogflow, Microsoft Bot Framework, Rasa, or a similarly capable stack—feel free to suggest the best fit.
• Seamless web integration (JavaScript widget or custom embed) that matches my site’s look and feel.
• A structured knowledge base I can update easily, covering our product catalogue and common tech issues.
• Intent training, fallback handling, and a simple way to escalate to live chat or email when the bot can’t solve the problem.
• Deployment, brief hand-off documentation, and a short video or call walking me through how to update or retrain it.

The focus is strictly on the website for now; other channels may follow later once the core experience is solid. Clean, well-commented code and a smooth, friendly user experience are essential.
