I will build ai voice agent for cold calling survey calls appointment booking with vapi
Larrie Daniel
About this gig
Missed calls are lost revenue. Slow follow-ups kill deals. Manual cold calling doesn't scale.
I build AI voice agents that answer calls, run cold calling campaigns, conduct survey calls, and book appointments automatically 24/7, without hiring staff.
Whether you need an AI receptionist for inbound calls, an outbound cold caller to qualify leads, or a survey agent to collect responses at scale, I design and deploy the full system using Vapi AI, Retell AI, and n8n automation.
What you get:
- AI voice agent setup (Vapi AI or Retell AI)
- Custom call script and conversation flow
- Cold calling, survey calls, or appointment booking
- CRM integration (GoHighLevel, Airtable, Google Sheets)
- n8n or Make.com workflow automation
- Call transcripts, summaries, and lead capture
- Human handoff when needed
Built with: Vapi AI · Retell AI · Bland AI · ElevenLabs · n8n · Make.com · GoHighLevel · Twilio
I've built voice agents for sales teams, service businesses, and agencies. Every delivery comes with a test call so you hear your agent live before it goes to work.
Message me before ordering I'll confirm the right setup for your use case.

FAQ
What platforms do you use to build the voice agent?
Primarily Vapi AI and Retell AI the two most reliable platforms for production-grade voice agents. I also work with Bland AI and Synthflow depending on your use case. ElevenLabs handles voice quality when a more human-like tone is needed.
Can the agent make outbound cold calls automatically?
Yes. I can set up an outbound calling campaign where the agent dials a list of numbers, runs your script, qualifies leads, and logs the outcome to your CRM all without manual effort.
What are survey calls and how do they work?
Survey calls are outbound AI calls that ask recipients a set of structured questions and record their responses. Common uses include NPS surveys, market research, customer feedback, and lead qualification. I design the question flow and connect responses to a spreadsheet or CRM.
Do I need a Vapi AI or Retell AI account?
Yes, you'll need an account on whichever platform we use. Both have free tiers for testing. I'll guide you through setup and connect everything during the build.
Can the agent book appointments directly into my calendar?
Yes. I can integrate the agent with Google Calendar, GoHighLevel, Calendly, or Cal.com so it books appointments in real time during the call without any manual step.
Will it integrate with my CRM?
Yes. I connect the agent to GoHighLevel, HubSpot, Airtable, Google Sheets, or any CRM with a webhook or API. Every call outcome, transcript, and lead detail gets logged automatically.
How natural does the voice sound?
Very natural. I use ElevenLabs or the built-in Retell AI voices both are human-like with low latency. You'll hear a test call before delivery so you can approve the voice and tone.
What if the caller goes off-script?
The agent is built with fallback logic for unexpected responses and a human handoff trigger for situations it can't handle. I design the flow to cover the most common objections and detours for your use case.
