Build a website (on standard CMS like WP, Joomla) for e-sport communities to advertise their community activities

Idea simplified: eSports Community platform for recruitment of online players and teams search. Find fellow players for popular multiplayer titles such as Call of Duty, Fortnite, League of Legends, CS: GO, Apex Legends or Rainbow Six Basically a network that mediates player groups and players. The goal is to enable the most precise mediation possible, with player and team characteristics, system, rankings, skills, hashtags and team -Presentations. In addition to the main occupation of transferring gamers, we want to offer teams many options: whether server lists, to submit their own news; Practice opponents, training partners or the next competition How it would work - admins add games/categories - Gaming Communities shall register, add logo and description of themselves - add an "advertisment" that they are looking for players to join in a respective game/category - they can "advert" they are looking for teams to have a match - players can search in database by game or for clans by filters, like Age, Games, other categeories as "pro" or "leusire" games there is a page with similar offer: [login to view URL] but we want to offer this as a free service ideally this is done on Wordpress or Joomla, with existing (and paid) plugins, so this can be maintained over couple of years. Please bear in mind, this is a private platofrm, no commercial implementation.
