WordPress Company Info Site -- 2

I run a residential rental property website on WordPress. I need an interactive AI chat assistant prototype that greets website visitors, answers property-specific questions (using a provided knowledge base/listing details), pre-qualifies tenants, and sends the chat transcript to our team via email.
Crucially, the AI must act as a visual tour guide: when a user asks about a specific room (e.g., "Show me the kitchen"), the AI must trigger the embedded property video player on the WordPress page to skip to that exact timestamp (e.g., jump to 0:45 seconds).
Scope of Work & Deliverables:
1 AI Conversation Design (Voiceflow):
Build a conversation flow that automatically initiates when a user lands on a property page.
Integrate a Knowledge Base within Voiceflow so the AI only answers using the specific details of that listing (Rent, security deposit, pet rules, utilities). 
Incorporate a pre-qualification flow (asking for name, email, move-in date, and income verification) before offering a calendar link to book a viewing.
2 WordPress & Video Player Integration (JavaScript API):
Implement a lightweight JavaScript listener. When Voiceflow outputs a specific metadata payload or custom command (e.g., command: "seekVideo", timestamp: 45), the script must instantly control the video player on the page (YouTube API, Vimeo API, or standard HTML5 <video> tag) and jump to that point.
3 Lead Routing Automation:
Set up a Webhook step at the end of the Voiceflow conversation that pushes the customer profile data and full chat transcript to a webhook (via Zapier or Make.com), which formats it and emails it to our property management team.
