Poker Coaches

[PokerProdigy]

Does anybody know of any good poker coaches for limit holdem? Because I have been playing a bit for the last 2 years and I feel like I just suck. I mean I have read alot of books and think I understand the concepts but I always seem to lose. I play NL holdem well and can consistently win money there, but when it comes to limit holdem I lose. So, I am wondering where I can find a good poker coach to show me what I am doing wrong at limit holdem, and how I can turn into a winning player.
