Craig S. the fact you're packaging this as a paid test first is smart, but I'd push you to think about whether you actually want a person or a system. I've built exactly this stack for agencies - Clay table with signal-based triggers refreshing weekly, scoring, pushing to outreach tools - and the real unlock is when the system runs itself and you just review outputs. The $3K/mo retainer model works but you'll hit a ceiling fast if the person leaves and takes all the tribal knowledge with them.... better to build the infrastructure so it's yours regardless of who operates it.
