Who it's for

Built for three kinds of client

Whether you run a business, an MSP, or an internal IT team, there's a clear way to put me to work.

For businesses

Offices & small businesses

No full-time IT? I'm your on-call engineer for the everyday problems and the emergencies — clear, friendly, and fast.

  • Offices, clinics, law firms, warehouses & branch sites
  • Computer, Office 365, Wi-Fi & network issues
  • New-hire setups, device refreshes, urgent outages

MSPs & field vendors

Reliable Chicago-area smart hands when you need boots on the ground — vetted, professional, and easy to dispatch.

  • Hardware swaps, installs, imaging & staging (Intune / SCCM)
  • Network, Wi-Fi & firewall (SonicWall / Meraki) checks
  • Site surveys, overflow & recurring coverage

The difference

Hire the engineer, not the markup.

Dispatch networks add a layer of coordination — and margin — between you and whoever actually shows up. With IT-OnCall, the senior engineer who shows up is me, every job, start to finish.

Dispatch network / MSP

  • Premium hourly rate built on a platform margin
  • Whoever's nearest gets the ticket — skill varies
  • Often locked into contracts or service bundles
  • You re-explain your setup to a new face each visit

IT-OnCall Services logoDirect

  • Competitive rate — no middle layer to pay for
  • The same ITIL-certified senior engineer every time
  • On-demand: one fix, a project, or recurring coverage
  • I learn your environment and keep the context

Opening, moving, or closing an office?

One engineer handles the IT side end-to-end — from delivery day to documented cutover. After-hours and weekend work available when the building requires it.

Move in

New office openings

Everything IT-ready by day one — receiving, staging, and building out the space.

  • Delivery-day receiving, unboxing & staging
  • Conference room setup & TV mounting
  • Rack build-out — firewall, switches & Wi-Fi APs
Plan my move-in →
Relocate

Office moves

Documented teardown at the old site, clean rebuild at the new one — nothing lost in between.

  • Port mapping & cutover documentation
  • Patch panel & rack reconfiguration
  • Desk-side setups & user readiness
Plan my relocation →
Move out

Office decommissions

Closing a site? Equipment comes down clean, labeled, and accounted for.

  • De-rack, inventory & labeling
  • Packing for relocation or disposal
  • Handover documentation of what went where
Plan my decommission →

Structured cabling runs are coordinated with your cabling contractor — I take everything from the patch panel up. See office setup & moves →

Word of mouth

What they say

Senior managers and partners who've relied on Mohammed for their IT — in their own words.

Mohammed is the go-to for anything IT. He works exceptionally fast and gives you 100% results, every time. You could send him an instant message and have a result within the hour — his work always went above and beyond.
Daisy Ayala
F&A Director
A top IT expert in his field. It's one thing to have IT knowledge, but very different when someone with his depth of experience is responsive and thorough with follow-up.
Nestor Popowych, AIA
Principal Architect, SAC Wireless
Mohammed has become my go-to person for all questions or needs related to IT. He is knowledgeable, available, and competent.
Kristen Bolinger Radwan
VP of Culture & Talent, Perma-Seal
On a large, time-sensitive merger project, without his 200% input and overtime work — including weekends — the project would not have been successful.
Edona Kurtolli
Director, Enterprise Customer Success, Exiger

How it works

From request to on-site, in four steps

Everything starts with the request form. It captures the location, systems, timing and urgency so the first reply is a scoped answer, not a round of questions.

01Request

Send the request

Use the form: where, what is affected, which systems, and when you need someone there. Attach photos or a scope document if you have one.

02Scope

Written scope and rate

I reply with availability, the scope and the applicable rate, usually the same business day. COI, W-9, NDA and site-access paperwork are handled before the visit.

03On site

The work gets done

The same senior engineer who scoped it shows up, does the work, and documents it: photos, notes, port maps or a change summary as appropriate.

04Close

Closeout and invoice

You receive a closeout summary and an invoice you can pay online by card or ACH. Recurring needs can move to a monthly block or backfill engagement.

Need a tech on site? Let's get it sorted.

Tell me the location, the problem, and when you need someone there. I'll confirm availability and scope fast — usually the same day.
