Google Workspace User Setup + Connecting them to Instantly.ai

Have 80 domains that need to have Workspace users created. Already have all the licenses purchased, simply need users to be created & domains to be added. I'm using domains from NameCheap. Lastly, I need these users to be connected to Instantly.ai.

This is a setup for email marketing. Need 3 users per each domain (240 total users.)

This will take 3-5 days. Must have experience/familiarity with Google Admin Panel, Google Workspace, Namecheap, & Instantly.ai

After this initial task I'll be paying for part-time tasks related to domain management & Instantly.ai (Occasional unrelated tasks)
