How do i make a script that sends two players into a server?

So, me and my friend are trying to make a "BEAST VS HUMAN", kind of like five nights at freddys. Neither of us are good at scripting, or knows basically anything. we wanted a main menu, where you would be queued to a match after clicking play. how can we make it so when there are 2 players in queue they will be sent into a server, when more people get queued they will be sent to a separate server? [each 2 ppl gets a separate server/match.]
