You Don't Need a $5,000 Marketing Agency. Here's What AI Can Do for $20/Month.
Let's talk real numbers.
If you're a small business owner, solopreneur, freelancer, or even someone building a personal brand or side project, you've probably looked into hiring a marketing agency — or at least thought about paying someone to handle your marketing. And you've probably seen the price tags: $3,000 to $5,000 per month for a basic package. Some agencies charge $10,000+ for the full suite.
What if you could do most of that yourself for about $20/month?
You can. Here's how.
What a Marketing Agency Actually Does
When you strip away the jargon and fancy proposals, most small business marketing agencies deliver some combination of:
- Writing blog posts and website copy
- Creating social media posts
- Writing email newsletters
- Basic SEO (search engine optimization)
- Creating simple graphics for social media
- Developing a content calendar
- Writing ad copy
None of these tasks require specialized expertise anymore. AI has changed the game.
The Cost Comparison
| Marketing Agency | DIY with AI | |
|---|---|---|
| Monthly cost | $3,000 - $5,000 | ~$20 |
| Blog posts (4/month) | Included | AI writes drafts, you review |
| Social media (20 posts/month) | Included | AI generates, you approve |
| Email newsletter (weekly) | Included | AI drafts, you personalize |
| SEO optimization | Included | AI tools handle it |
| Your time | ~2 hrs/month (reviews) | ~5-8 hrs/month |
| Annual cost | $36,000 - $60,000 | ~$240 |
Annual savings: $35,000 - $59,000.
Yes, you'll spend more of your own time. That's the trade-off. But we're talking 5-8 hours a month, not a full-time job. And you'll actually understand your own marketing — which makes you better at everything else in your business too.
What You'll Need
The core toolkit for DIY marketing with AI:
- An AI assistant (like ChatGPT or Claude) — $20/month for the pro version. This handles copywriting, brainstorming, strategy, email drafts, and more.
- Canva (free tier) — for social media graphics, presentations, and basic design.
- Your existing email platform — most website platforms (including Ghost, which powers this site) have built-in newsletter tools at no extra cost.
Total: about $20/month.
The Honest Trade-offs
We're not going to pretend DIY is perfect for everyone. Here's when you might still want an agency:
- You have zero time. If you genuinely can't find 5-8 hours a month, outsourcing makes sense.
- You need high-end creative work. AI can't match a top-tier creative agency for brand campaigns, video production, or complex design.
- You're scaling fast and need a team managing multiple channels, paid ads, and sophisticated analytics.
But for the vast majority of small businesses, solopreneurs, and individuals? The DIY approach gets you 80% of the results at 1% of the cost. And that's a trade-off worth making.
This Applies to Personal Projects Too
Everything in this article focuses on business marketing, but the same principle applies to any situation where you'd pay someone for a service you could do yourself with AI.
- Building a personal portfolio or blog — no need to hire a web designer
- Writing a resume and cover letters — skip the $300 resume writing service
- Creating content for a side project or hobby — AI handles the heavy lifting
- Managing personal social media for a job search or personal brand — AI can help you stand out
The pattern is always the same: figure out what you're paying for, then see if AI can help you do it yourself. Usually, it can.
