I have built agents that read a support question or an Instagram DM, look for the answer in a knowledge base, and pass the work on to a specialist agent or to a person on the team. This page shows each one, what a build costs and how one goes.
Three parts of one IT troubleshooting engine, built for one client, and an Instagram agent built to book consults in the DMs.
I built a chat that walks IT support through a diagnosis one step at a time, behind a dashboard that tracks sessions, confidence, knowledge base coverage and skill gaps. Summary emails go out automatically.

Part of the same engine. A product manager agent reads the issue, a summary agent condenses it, and a switch hands it to one of four specialist agents, each with its own OpenAI model.

Also part of the engine. It takes a question and any files from the app, reads images, PDFs and text files, searches the knowledge base, runs a web search only when needed, and sends one answer back to the app.

I also built an Instagram agent for an agency that sets up booking agents for med spas. It was made to answer DMs from each spa’s own knowledge base (a Google Doc their team edits) and book consults inside the thread. I built it with ManyChat, 7 n8n workflows, an OpenAI model (gpt-4o-mini), GoHighLevel and Google Calendar. It was a client build, delivered, and the engagement ended in July 2026.
The Instagram agent had a rule for messages the AI should never answer.
The rule
Medical, refund, legal or “talk to a person” messages were never answered by the AI. It took a callback time and contact, then alerted the team.
Someone unsure about a date got a callback too, flagged for the team.
You get a written scope and a fixed price for each milestone. You sign off before I build anything, so there are no surprise invoices.
$600 to $1,800 per build

$200 a month

Each build is split into fixed-price milestones. Smaller job? Hourly consults and fixes from $15 an hour.
01 · Day 1
A 30-minute call. I look at your current setup, ask where the hours go, and point out what is worth automating first.
02 · Days 2 to 3
Deliverables, timeline and a fixed price per milestone, in writing. You sign off before I start.
03 · 1 to 3 weeks
I work in your tools, so the handoff is clean. You see working pieces every few days, with a weekly check-in.
04 · Final week
It runs on your accounts, with full documentation and a recorded walkthrough. Yours to keep.
Most builds take 1 to 3 weeks from signed scope to handoff. Full audits and small fixes take 3 to 5 days. AI agent and knowledge base projects take 2 to 4 weeks, depending on their size.
Your hosting (AWS or GCP), domain costs and third-party API spend such as OpenAI, Apify or Pinecone. They are listed in the scope, and I don’t mark them up.
Yes. Every build comes with documentation, and I can run paid training sessions so your team can extend and fix the workflows without me.
