There are some coaches that would be willing to coach you for free maybe look for a bit or maybe join a team that has a coach and ask the coach to look at you individually or something. Also you say your 17 make sure to still pay attention to school even if you get good at Valorant its never gaurenteed that you will be able to go pro or make a living out of it theres a very limited amount of people in tier 1/2 and sometime it can be a matter of luck. Also who knows maybe what you learn in school can help you work in Valorant esports somewhere else maybe not player. Like Im studying data science n stuff rn and maybe due to my passion in Valorant I might become a pro Valorant analyst as a hard stuck plat and Im already currently coaching a ascendant team
