Just sold a chatbot for $6.5k, which options do I have now?

So funny story, just sold a $6.5k chatbot to a client, was thinking to use elevenlabs for text & voice… but are there any other options? For text at least?

Context:

Company: tree-planting b2b company from germany.

Context → What the client wants the bot to do:

Core Functions:

Replace phone calls: 20% of people don't want to call - bot should capture these
Automated quote generation: Customers should be able to spend €100,000+ without ever talking to humans
Product consultation: Explain offers/products
Lead qualification: e.g. Filter out 1-10 person team events ("we don't offer that, minimum 15 people")
Direct checkout: One-click links to Stripe/PayPal for immediate bookings
Escalation to humans: When bot hits limits → "Sorry, too complex, human will contact you within 8-16h’’

Placement:

Website integration: Support bot bottom right like other companies
Proactive messaging: "No interest in calls? Chat with our Plenty"
Cross-page tracking: Bot follows user through website

Optional/Nice to Haves:

Gamification:

CRM integration: Automatic routing to responsible people (Alex for team events, etc.)
Wheel of fortune integration: "Before we start, want to spin our wheel?" → 10% discount, free tree certificate, etc.
Quiz games: "Let's play a little guessing game"
Emotional connection: Tell stories about Mammoth trees
