Presale questions

Hello, i’m looking a functionality like this: https://plazuela-municipal.cluvi.co/plazuela-municipal-granada/reservar

Basically it is that people can choose the number of people or guests, date and hours available for that date.

Could you achieve this with your plugin? Is it necessary to buy a license?, the design could choose one of your templates, I am interested in the functionality, also the support that you can give me.
