[HIRING] Vapi + n8n + Twilio Developer for Full AI Voice Agent Build (Paid Project)
Hi everyone,
I’m looking for an experienced automation engineer who can help me build a full AI voice agent system using n8n + Vapi + Twilio + CRM integrations.
This is a paid freelance project with clear requirements and a defined scope.
I’ll keep this as concise and technical as possible so you know exactly what’s involved.
:pushpin: Project Overview
I need to build an outbound AI voice agent (“Morgan”) that will:
Call prospects from a lead list
Qualify them using structured criteria
Book meetings into a scheduling system
Score the lead in real-time
Trigger alerts for high-intent leads
(Optional add-on) Live human handoff using Twilio conference
All of this needs to run through n8n workflows acting as the backend glue layer.
:puzzle_piece: Core Requirements

  1. Vapi Voice Agent Setup
    Natural, robust conversation design
    Interrupt handling
    Memory state management
    Event/webhook routing into n8n
    ElevenLabs voice integration
    Structured prompting for qualification logic
  2. Lead Management + Scheduling
    CSV upload (Name, Company, Phone, Context)
    Controlled calling times (e.g., 09:00–17:00 weekdays)
    Auto-dial through list
    Meeting booking via API (Calendly/Google Calendar/etc.)
  3. Real-Time Lead Scoring Engine
    Scoring based on:
    • Budget mentioned
    • Timeline urgency
    • Office size requirements
    Confidence score output (0–100%)
    Hot lead detection (90%+)
  4. Alerts & Notifications
    SMS/email alerts
    Optional Slack or Teams webhook
    Structured JSON payloads
  5. CRM Integration
    HubSpot, Salesforce, or Pipedrive
    Log call outcome, transcript, recording URL
    Update lead stages automatically
  6. Optional Premium Feature — Live Handoff
    If you have experience with Twilio conference flows, please mention it.
    This feature includes:
    Creating a conference room
    Moving caller → conference
    Dialling in a human agent
    AI steps back once handoff completes
    Latency target 8–15 seconds
    :hammer_and_wrench: Tech Stack
    You must be comfortable with:
    n8n (webhooks, conditional logic, CRM modules, async workflows)
    Vapi.ai (events, functions, call flows)
    Twilio (voice, outbound calls, conference API)
    OpenAI / ElevenLabs (integration level only)
    :memo: Deliverables
    Fully configured system
    Clean n8n workflow(s)
    Documentation for future maintenance
    One handover/training session
    30 days of bug support after delivery
    :money_bag: Budget
    Flexible depending on experience, but roughly:
    Base system: £800–£1000
    Live handoff add-on: £800–£1,200
    Paid through the platform of your choice.
    :envelope_with_arrow: How to Apply
    Please reply with:
    Your experience with Vapi + n8n + Twilio
    Examples of similar voice-AI or automation projects
    Your availability
    Estimated timeline
    Your pricing for:
    Base system
    Live handoff feature
    I’m ready to start immediately for the right developer.
    Thanks!

I am only open for remote oportunities for now

If you need I am available here:

Here is my portfolio:

I’m also a full-stack developer with the right Gen AI experience, which makes me a solid plus for your team[but right now only vibecoding]

Check my recent gen ai projects… I built a native Android automation agent too. It’s worth a look:

I can build complex AI automations directly in code, not just inside n8n.

I recently started posting my n8n work on YouTube with explanations:

Fun fact… I even made an n8n workflow to find a few n8n project leads for myself :skull::skull::skull: so I truly believe in what I do…

Hey!
We’ve built systems using ElevenLabs, VAPI with Frejun, Twilio, OpenAI, GHL, Airtable, and Pipedrive. We’re also proficient in JavaScript.
With this combined experience, we’re confident we can build something robust for you.

Feel free to email us at [email protected] to discuss the specifics or set up a quick call!

I’m an experienced automation engineer with strong expertise in n8n, Vapi, Twilio, and CRM integrations. I’ve built similar AI-powered voice agents before, including lead management workflows, real-time scoring, and automated meeting scheduling.

I can handle the full development of your AI voice agent — from configuring the Vapi voice system to integrating it with your CRM and adding optional live human handoff. I focus on building clean, efficient workflows in n8n to ensure everything works seamlessly.

Happy to discuss the details and share a proposal with timelines and costs

This project fits very closely with the systems we build at Hashlogics.com, where our team can deliver full AI-voice pipelines using Vapi + Twilio + n8n with structured scoring, CRM syncing, and clean event-driven call flows. We’ve implemented outbound agents, multi-turn state management, qualification logic, and live human handoff patterns across several client deployments.

For context, one of our flagship automation builds is our ESG Sustainability Platform — a full compliance automation system that collects disclosures, validates evidence, and generates audit-ready ESG reports in real time: :open_file_folder: Full Case Study.

We applied the same orchestration patterns in QA.Tax, an IRS “Escape Plan” assistant that interprets complex tax rules, reviews uploaded documents, and generates personalized actions. A short walkthrough — it shows how we handle structured prompting, memory, evidence extraction, and deterministic scoring logic.

On your scope, everything is well-defined. The only items worth clarifying live are the exact scoring formula, how state should be persisted back to Vapi mid-call, the CRM field mapping, and the latency expectations for the live handoff. Our company rate ranges $50–$80/hr (negotiable), but the most accurate approach is to have a short call, break the requirements down module-by-module, and confirm if anything is missing before estimating the Base System and the Handoff module.

Happy to walk through how we’d implement it step-by-step whenever you’re ready!

Hey B10_Jr

I got you, I have been building all forms of automations for the past 2 years and have built 100s of flows for my clients. Have worked with all sorts of companies and gotten them 10s of thousands in revenue or savings by strategic flows. When you decide to work with me, not only will I build this flow out, but also give you a free consultation like I have for all my clients that led to these revenue jumps.

I have built a similar workflow like this for one of my clients. I can not only share that but also how you can streamline processes in your company for faster operations. All this with no strings attached on our first call.

Here, have a look at my website and you can book a call with me there!

Talk soon!
