Many people use this business model + it breaks my first rule.
"Every action must drive to continuity."
The challenge with this business model...
Once you've made the introduction, how do you get paid... well even once + more importantly over + over again.
One way to resolve this challenge is to join Meetup + Fizzle + any association (like a chamber of commerce). Watch what they do. Clone what seems good to you.
Call your service something people expect to pay for - membership based course or forum or association, where people expect to pay a monthly fee.
If you join Fizzle, I'm pretty sure I still have a coupon or link to a 5 week free trial.
Meetup groups provide good education. Meet the organizers + just flat out ask them how they monetize their Meetup... or better...
Start a podcast + interview people running introductory services + ask them how they monetize.
People tend to be more open to "interviews" where they tell all, then just conversations.
When interviewing, there's something for you + the person you're interviewing.
