A few months ago I told a client that their options for Power Pages licencing for one site to be accessed by a few hundred anonymous users was £0.20 per user per month on Pay as you go or £61.60 for 500 users per month on Subscription. I found these two options on the microsoft power pages pricing web page.
They are looking to move from trial to production but I cannot see the pay as you go option in the pricing anymore. Has it been removed? I can see in the portal that you can get the option of using an azure payg subscription when you create new production environment but cannot see confirmation of the costs on Azure site? They will have dataverse for their forms and one user with power automate licence to use the dataverse connectors.
