Not sure how it holds up in this day and age but a common setup was to have 3 products: free, cheap, expensive.

The free one gets people in the door. Cheap is could be something like a book or paid tool or course. And the "expensive" would usually be consulting but could also be a more premium tool or retainer service.

So your suggestion seems to fit the model.

I know LLMs will change the developer education landscape but I really hope it doesn't kill it. Interesting times.
