That's a very broad question, there are leaks in your game (in everyone's) which if you patched up would improve your winrate a lot, poker tracker will help you find what needs to be fixed. This could take a day, a month, or if you don't work on it, never.
You say a lot of $ amounts but none of it means anything without the number of hands and even when you do get to win $50/day on average then you're still going to have frequent days where do finish with -$100.
It's just a question of the time/effort you put in as to how long it will take, everything you need to learn is readily available on the internet, poker tracker or holdem manager will help too. Other than that, just find a pen and paper and analyse various situations, hand ranges, bet sizes etc.
