Paid WiFi Network Deployment for Festival

I have an opportunity to deploy a WiFi network at a week-long event with poor cellular connectivity.

Details:

1. Symmetric 1 Gbps fiber network connection on site.
2. Some open fiber on-site for networking.
3. Max 2000 clients, but more likely 1000.
4. The demand is there, attendees complain each year.

Questions:

How would you deploy this is one day for an event in 10 days (need to order equipment) to work reasonably well? It's acceptable to limit access to X number of users per day.

Which network equipment? Router/Switches/AP

I've spoken with www.mywifinetworks.com and they seem to confirm their software will work for the paywall. I've seen Ubiquiti has built in options for Stripe, but seems the integration lacks a secure connectivity to the Stripe API.

Any ideas are welcomed.

If you're in Iowa and want to work on a side-hustle, that would be an option.
