Get into some sort of pro league such as RLCS as the oldest pro player.
I am 26, go by Yesper, and I have been playing Rocket League since season 1. I am a kbm player and my peak mmr is ~1825. 6mans rank is B currently. I've played in over 100+ tournaments and been to the finals of the RLCS qualifiers. I also have experience on several teams as well as owning several of my own at one point. I am currently looking for a quality team that has played high level players and have been able to hold their own. My highest MMR may not be that high, but with my past teams I have beaten 1900MMR players and played against top 20 global players. I am in the NA region playing from Missouri so both east and west servers.
