Question looking for multiple-person workshop

Hey,

i am a member of a club, that wants to start working with AR. Currently we are discussing to buy the hololens2, but the problem is we basically do not know anything about AR. We would be about 10 people and we are looking for a guided interactive workshop. There are udemy courses and such, but as i said, we would like to attend a workshop as a group and have a speaker to communicate with. Anybody knows were to start?

thanks in advance
