Actually no. No company wants to deal with 100's of different agencies with different terms, and it's unlikely that someone out there is doing 'revisions etc' i.e. actual work and making $1M, there's some pricing misinformation or someone is selling some kind of service. Certainly it's not a template.

Companies offering SaaS where there's very low friction - yes. But agencies like that, unlikely.

I'm already in this boat the last thing we want is every single person to be on different terms.
