Mikrotik router suggestion

Hi, everyone! I am new to this forum and this is my first post. I am going to start a small ISP using fiber optic. Can anyone suggest me a mikrotik router which can support from 100-200 users at a time when running firewall, queues and some vlans. Currently my budget is low so please don’t suggest me something like CCR. I will buy them if needed in the future but for now please suggest me something to support this requirement. Will Hex do the trick?
Thanks In Advance.

Following.. interested to know your recommendations.. Thanks!
