Where this starts
The opportunity on one page: what it is, what checked out, and what we do not claim.
What you would be selling
The thing that changes hands for money, written as an offer a buyer could accept today.
The field: who is already there
The people already selling into this, what they charge, and where they leave the door open.
The numbers
Pricing and the numbers behind it. Anything we could not verify is marked missing, never made up.
The case against
The case against, at full strength. Meet the objection here, before a customer makes it.
What you build
What to build, in what order, and what to build it with. Includes what to leave out at first and what would stop this.
How the first customers find you
Where your first customers come from. Named channels, the first group to sell to, and the signals that say stop.
How it runs once it works
How it runs once someone pays. Delivery, capacity limits, the compliance you cannot skip, and where the manual work sits.
Your first fortnight
Six steps for days one to seven: confirm the buyer, size the smallest paid offer, pick one channel.
The toolkit
The named tools, services and suppliers this runs on, with what each one is actually for.
Copy you can paste
Launch copy you can send today: listing page, outreach, social. Checked against the sources, like the research.
How to know in 30 days
The one month test: what to run, what number to watch, and the reading that says walk away.
Everything we read, once
Each check, what it found, and the source behind it, without hunting through the plans.
Every check, in full35 sources
Every check this pack faced, each verdict, and a clickable source behind every claim.
