About this Gig
Need an AI voice agent that handles inbound calls 24/7, books appointments, qualifies leads, or runs outbound campaigns without hiring a call centre?

Inbound call handlers (FAQ, support routing, intake)
Appointment-booking agents (Cal.com, Calendly, GHL)
Lead-qualification and sales-discovery agents
Outbound calling for follow-ups, surveys, reminders
Multi-language voice agents
Voice agents with custom voices and personality
PLATFORMS
Vapi, Retell AI, OpenAI Realtime, Twilio, Bland AI, ElevenLabs
WHAT YOU GET
Working voice agent with phone number provisioned
Custom prompt, system instructions, and guardrails
CRM and calendar integration (HubSpot, GHL, Calendly)
Call transcripts and analytics
Test call scripts so you can verify before launch
7-day post-launch support
Tell me what call flow you need ('caller says X, agent does Y'), and I'll quote within the hour.

FAQ
What is Vapi and why use it?
Vapi is the leading AI voice infrastructure — it lets voice agents sound human, integrate with any tool, and scale to thousands of calls. I also work with Retell AI and OpenAI Realtime if Vapi isn't the right fit for your use case.
Will the voice sound natural?
Yes — I use ElevenLabs or Vapi's built-in voices that are nearly indistinguishable from human voices. You can pick gender, accent, and tone, and even clone a voice on request.
What ongoing cost should I expect?
Vapi/Retell typically costs $0.05–$0.10 per minute of conversation, plus phone number rental (~$2/month) and LLM API costs. For a small business handling 100 calls/month, expect $30–$80/month total. I'll estimate this for your specific volume before you order.
Can the agent transfer to a human?
Yes — I can configure warm and cold transfers to your team, with custom triggers (e.g., "transfer when caller asks for refund").
Will it integrate with my CRM and calendar?
Yes — HubSpot, GHL, Salesforce, Pipedrive, Calendly, Cal.com, Google Calendar, and most others. Custom integrations via API.
Do you provide source code and configuration?
Standard and Premium include full Vapi/Retell project export, prompts, and integration code so you own the agent.
