How to Sell AI Video Production Services to Other Agencies and Earn 3000 to 8000 per Month Using Synthesia and Descript

We built an ai video production service business in under a week using Synthesia and Descript. We landed our first agency client at $3,500 for a 10-video package. This guide covers how to price it, which tools to use, and how to find agencies ready to pay.

Imagine waking up to a Stripe notification for $4,000. You did not film anything. You did not hire an editor. Your AI tools handled the production while you handled the client relationship. That is what this service looks like when it runs.

What Is an AI Video Production Service Business and Why Does It Matter?

An ai video production service business means you use tools like Synthesia and Descript to produce professional videos for clients without a camera, studio, or editing team. You sell the output, not the software.

Agencies are the best clients for this. They already have clients who need video content. They do not want to build the capability in-house. They will pay $3,000 to $8,000 per month to white-label your service and resell it at a markup.

The market is real. According to Wyzowl's 2024 State of Video Marketing report, 91 percent of businesses use video as a marketing tool. Agencies are scrambling to offer it without hiring full video teams.

Which Tools Should You Use?

Three tools cover everything you need to run this service profitably.

We use Claude to write every script before it touches Synthesia. ChatGPT works too, but Claude handles longer briefs and multi-video series better in our experience.

Your total tool cost runs about $133 per month. A single $3,500 client covers 26 months of software.

How to Get Started Step by Step

• Set up your Synthesia account. Choose the creator plan at $89/month. Pick 3 avatars that look professional and neutral.
• Set up Descript at $24/month. Connect it to your workflow for caption generation and filler word removal.
• Build a sample package. Create 3 demo videos: one explainer, one product walkthrough, one testimonial-style. Use a fictional brand.
• Price your packages. A starter package of 4 videos per month runs $1,500 to $2,500. A full retainer of 10 to 15 videos runs $3,500 to $8,000.
• Find agency targets. Search LinkedIn for "marketing agency" plus your city or niche. Filter for agencies with 5 to 50 employees. These are too big to ignore video and too small to have a video team.
• Send a cold outreach message. Keep it under 100 words. Attach one demo video. Offer a free pilot video with no commitment.
• Close with a white-label offer. Tell them you will brand everything under their agency name. They resell to their clients. You stay invisible.

What to Watch Out For

Synthesia avatars are improving fast but they still look AI-generated to trained eyes. Some agency clients will push back if their end clients notice. Be upfront about this in your pitch. Position it as scalable content, not broadcast-quality film.

Descript's transcription is accurate about 95 percent of the time. That means 1 in 20 words may need a manual fix. Budget 10 to 15 minutes of review per video. Do not promise zero editing time to clients.

Also, agencies move slowly. Expect a 2 to 4 week sales cycle even when they are interested. Follow up twice before you assume they are not buying.

---

Someone in your market built this exact service last month. They already have two agency clients on retainer. While you read this, those agencies are reselling AI video to their own clients and paying that person every month. The gap between you and them is not skill. It is setup time.

Zero Day AI gives you mission files that tell your AI exactly what to build. You paste. It builds. You walk away with a working system in under an hour. Try it for $1. Two weeks. Full access. If it is not for you, cancel. But every week you wait is another agency signing with someone else.

What to Do Right Now

Open Synthesia today and create your free trial account. Build one demo video using a fictional brand brief. That video is your sales tool. Send it to five agencies this week with a one-paragraph pitch offering a free pilot.

You do not need a website, a logo, or a business plan to start. You need one demo video and five cold messages. That is the entire first step.

Waiting another week does not make this easier. It just means someone else gets those agency contracts first.
