10 ways to make money with Idea Sex Group

i created a group here in Riga, Latvia, where entrepreneurs (and not only) can share their business ideas (and not only) in order to evaluate ideas, find partners, employees, investors, etc. group meets once a month (for now due to covid restrictions) live and meeting starts with some presentation from successful entrepreneurs or idea pitches, etc. The meeting is free of charge (for now).
I'm looking for at least ideas on how to turn those meetings into profitable business ?!

1. 1. charge a fee to attend meetings, but this can be done after at least 10 successful meetings

2. Offer consulting services to people who want to start their own Idea *** Group.

3. Hold events and workshops on various aspects of Idea *** Group.

4. Create a blog or podcast about running an Idea *** Group.

5. Write a book about starting and running an Idea *** Group.
