Bite-size, problem-focused, instructor-led, hands-on technical workshop

I am seeking advice from HN experts to grow my workshop sessions.

I am offering problem-focused technical workshop sessions and have 2 learners signed up for a few classes. Here's the site https://avnicloud.corsizio.com/

How do I reach a large number of technical learners or college graduates?

I also want to offer my platform to instructors interested in providing technical training.

Please share your opinion, good or bad, about the growth potential.
