Huawei B593 LTE Router to RB750 Hotpot Billing System

RouterOS Beginner Basics
1

I am planning to buy Huawei B593 LTE router and setup a small hotspot business.

  1. I would like to print unique usernames & passwords for each customer on 3hour limit and then it automatically disconnects.
  2. Set it up to restrict torrent downloads.
  3. The customer cannot use his device to share his connection.
  4. Do I still need a hotspot billing software like engagehotspot.com?
  5. or can Mikrotik RB750 do this?

Any help would be appreciated.
