Multiple Brokers Meetings at one time.

[Forte]

I am looking to set-up 30 "Broker" meetings.  These Brokers are not related to my company.

• Brokers already have their own Zoom accounts. 
• Each Broker meeting would be reoccurring over 5 days and run 8am-5pm.   
• Each of these Broker meetings would have  Customers join at various times during the day.  
• I would like to give the Customers a single link to join a specific Broker  ( Link for Broker 1, Link for Broker 2, etc.). 
• I would like to schedule these 30 meetings and allow the Brokers to have full access (start meeting without me)

What is the best way to accomplish this?

• Have the Broker assign me scheduling privileges?  How do I manage and review these schedules?
• Create a single account and add licenses for each Broker (the project is temporary and I don't want to hijack their Zoom accounts) That happened to one of my Zoom account (un-linkable).
• Create a single account and add 30 licenses under alias emails, then create the meetings and add the Brokers as co-hosts (would the account with 30 licenses be able to run these 30 meeting simultaneously?)

I have spoken with Zoom help on the phone and not had reassuring answers.  Appreciate any help you can offer!
