It does not bode well that you have been on 2+2 for three years and have 24 posts, not one of them in a strategy thread. It also doesn't bode well that you don't have tracked records or a bankroll. I don't think that you work on your game anywhere near enough to be a semi-pro, or even a good rec.
If you want to do this, search the LLSNL
winrates, bankroll, and finances thread for "confidence interval." Cliffs, you need at least 500 hours to have a decent idea what your winrate is, even if you play a low SDV game.
Then also read all of the threads in the Best Of LLSNL sticky. Start posting in strat threads, posting your own hands for discussion etc. I'm guessing you were playing $2/5 in your big win. Stop it. Use that $2K as your initial bankroll, and use it to play $1/2. If you build it up to $5K, you can start taking occasional $2/5 shots.
