I want to put an always-on AI voice agent in charge of one thing only: generating brand-new cold leads by telephone. I will provide the target market, ideal-customer profile, and high-level talking points; you build, train, and deploy the agent so it can dial prospects, hold a natural conversation, qualify interest, and pass every promising contact straight into my CRM. The agent must: • sound human and handle common objections in real time • record, transcribe, and store every call • schedule callbacks or meetings on my calendar • respect local calling regulations (TCPA, GDPR where applicable) I’m comfortable with Twilio Voice, Dialogflow, ElevenLabs, GPT-4, or any similar stack—as long as call quality and scalability stay top-tier. Show me a short architecture outline, the tools you plan to use, and links to past voice-AI projects so I can gauge fit quickly. Deliverables • Fully deployed phone agent reachable via a dedicated number • Real-time CRM or Zapier integration for lead handoff • Setup and usage documentation plus editable call scripts • One week of post-launch tuning and support If you have proven experience building voice AI for outbound sales and can hit these marks, I’m ready to get started right away.

I’ve successfully delivered multiple high-end automation projects—you can see the results and client feedback on my profile—and I’m ready to deploy this exact voice-AI stack for you. I specialize in using n8n to orchestrate "best-of-breed" tools like Vapi, ElevenLabs, and GPT-4o, achieving the sub-second latency required for natural sales conversations. How I will hit your marks: The Build: I will configure a Vapi + Deepgram + ElevenLabs pipeline. This setup is the gold standard for avoiding the "robotic delay" and handling "barge-ins" (when a prospect interrupts the AI). The Logic: I’ll use n8n to build a custom "Brain" that fetches leads from your CRM, triggers the calls via Twilio, and then pushes transcripts and booked meetings back into your calendar in real-time. Compliance: I’ll ensure the system respects local regulations by implementing time-of-day calling windows and automated opt-out (DNC) lists. Deliverables: Dedicated Phone Agent: Reachable via your own Twilio number. n8n Workflow: A fully transparent, editable orchestration layer (no vendor lock-in). CRM Integration: Real-time data handoff Support: 7 days of post-launch tuning to refine objection handling. Because I have completed similar orders, I can move much faster than someone starting from scratch. I’d love to show you a demo of my previous voice-AI work—when are you free for a 10-minute chat?

Hi, Your vision for a focused, always-on AI voice agent dedicated solely to outbound lead generation is exactly the kind of high-impact automation I enjoy building. I would design the system using Twilio Voice for call handling, OpenAI (GPT-4/4o) for dynamic conversation logic and objection handling, and ElevenLabs for natural, human-like voice synthesis. Calls would be recorded and transcribed in real time, stored securely, and synced directly into your CRM. Calendar booking would integrate via Google Calendar or Calendly API, and compliance layers (TCPA/GDPR) would include consent handling, call-time restrictions, opt-out detection, and logging. High-Level Architecture: Twilio (dialing + call routing) → Webhook server (Node.js) → GPT conversation engine → ElevenLabs voice synthesis → Transcription + recording storage → CRM + calendar integration. The agent would be trained on your ICP, objection scenarios, and qualification logic to ensure consistent, high-quality conversations while maintaining scalability. I’ve worked on AI-driven automation systems involving voice workflows, real-time transcription, and CRM integrations, and I’d be happy to share relevant examples privately. Looking forward to discussing how we can deploy this efficiently and at scale.
