Should you hire a marketing consultant or an agency?
Short answer: hire an agency if you need many channels run by a team and can fund a retainer. Hire a consultant if you need one accountable person to build the system, show the numbers, and hand you the keys. Ask either one the same question first: what do I own at the end?
Reviewed 2026-10-01. I am a consultant, so I have a stake in this answer. The agency price range below is from an agency's own published page, not from me.
The two models are paid differently, so they behave differently.
An agency sells capacity: a team, a monthly fee, a bundle of hours or deliverables. A consultant sells a result you can point at: a funnel, a tracking setup, an automation. Neither is wrong. They fit different problems.
The risk with a retainer is not the fee itself. It is that the fee keeps running whether or not the work compounds. One agency operator's 2026 pricing guide puts most retainers between $5,000 and $40,000 per month, with small-business engagements starting near $1,500 and enterprise programs above $75,000.

| Agency retainer | Solo consultant (me) | |
|---|---|---|
| Typical monthly cost | $5,000 to $40,000 for most retainers; small-business work from about $1,500 (Chatter Buzz Media, 2026) | Growth engagement $1,500 flat plus $750 setup; diagnostic $7,500 one-time |
| Capacity | A team across design, media, content | One person. No design bench, no video team |
| Ownership at the end | Depends on the contract. Ask in writing | You own everything built |
| Best for | Many channels at once, steady weekly output | One or two lead channels, a funnel or system to build and measure |
| Main risk | Paying for a fixed block of time in a slow month | No backup if the one person is out; no capacity for large creative volume |

What people push back on, answered straight.
"One person cannot cover everything." Correct. If you need weekly video, a design team and a media buyer at once, you need an agency. I cover the part that decides whether the phone rings: the ads, the landing page, the follow-up, the tracking.
"Agencies have a track record. You are new." The brand is new (launched August 2026). The operating record behind it is not: a Chico's FAS director role with $1B+ P&L planning, a COO run from $2M to $18M over four years, and a pest-control company I founded at $500K+ ARR. (Source: the proof page and my résumé.)
"Show me a result." 79 leads from $1,202 of Meta spend in 30 days, about $15 per lead, on my own business. A lead is not a booked job. This does not predict your cost per lead in another market. (Source: first-party Meta Ads reporting, 2026. Full case file: the $1,202 campaign.)
Five questions to ask either one.
- What do I own at the end? Ad accounts, landing pages, tracking, automations. Get it in writing.
- What number will you report? Leads, booked jobs, cost per booked job. Not impressions.
- Who actually does the work? The person on the sales call, or a junior you never meet.
- What happens in a slow month? Does the fee change.
- How do I leave? Notice period and handover.

Direct answers.
Should I hire a marketing consultant or an agency?
Hire an agency when you need a team across many channels at once and can fund a retainer. Hire a consultant when you need one operator to build the system, hand it over, and stay accountable for the number. The deciding question is who owns the work when the contract ends.
Can a solo consultant really replace a marketing agency?
For a business with one or two lead channels, often yes. For a business that needs weekly output across a dozen channels, no. I am one person. I do not have a design bench, a video team, or a media buying floor, and I will say so before you pay.
Is a marketing agency retainer worth it?
It is worth it when the retainer buys output you cannot build or staff yourself and you can measure what it produced. It is not worth it when you cannot say what you own after month six. One published 2026 range puts most agency retainers at $5,000 to $40,000 per month.
What results has this AI marketing consultant actually gotten clients?
The number I can fully document is on my own business: 79 leads from $1,202 of Meta ad spend in 30 days, about $15 per lead, at Mosquito Shield. It is not a client result and it does not promise your cost per lead. Client work is listed with status labels on the proof page.
What does working with you cost?
Fixed prices, published. The growth engagement is $1,500 per month flat plus a $750 setup. The one-time diagnostic is $7,500. Lead automation is $149 per month plus a $750 setup.
