Error creating service "default_portal" from offering "portal" and plan "standard"

Hi,

I am trying to practice the tutorial given at this link (https://www.youtube.com/watch?v=tG_oUPs67CY). When I try to deploy MTA, I am thrown "404 Error" for "portal" service with "standard" subscription. I have explored everywhere in my 'trial account' including services, subscriptions and other sections, but I could not find the portal service.

Can some please help me with finding the portal service or completing this tutorial with an alternate resource. I am pasting below the deployment log from terminal.
