As someone who's been around a lot of tournament organizers for pug group-style or sized tournaments, this is the least planned so far that i've seen. Before you post to a community forum about it to gauge interest about one of the many concept tournaments i've seen pop up recently you need
- maps
- format
- tourney system (match.tf, faceit, toornament, essentials, etc)
- clearly defined rules that don't blow (the threshold for comp on TF2center is still at least 300 hours, and forcing teams to take on new players wont be fun for either experienced or new players)
- a central place of communication (usually discord)
- some experienced mods to help you get your stuff running
- at least a loose schedule/timeframe
- pretty much anything other than "hey guys i have this half-baked idea and am gonna host a tournament for it and it'll get massive!"
There's a ton of shit that goes into tournament organizing and frankly you don't seem very prepared to post about it, let alone host.
