Help with SNG game

[foxfox1]

I started playing sngs about March of 05. I've cleared about 30-40k in that time playing the 20s for about a month and the 33s since then. Recently, I dropped about 1500, I attribute mostly to poor playing after my first 20 buy in drop and getting weak and just squeaking into the money giving myself no shot at 1st. So, I dropped to the 20s and have just been hovering at about the same bankroll over the past 4 days. I don't know if this is the worst run I've ever had or if my play has just deteriorated. I would really like it if I could get with some type of SnG coach or something. Please help.
