Want to Redesign with beaver

I want to redesign my existing Elementor website ( carpetcleaningphiladelphiapro.com ) using Beaver Builder. Additionally, I would like to set up the following use case. Could someone please guide me on the additional requirements for this use case?

  1. Selected employees will be registered and have accounts on the website. After logging in, they will enter data into a form related to their current job (with several options to choose from). After entering the data, they will submit the form. Only the admin can access this data.

  2. These employees can also upload/download and edit if needed ppt xls and docx files on the website if needed.

This entire system will only be available to registered employees.

Thank you
