Beta Help Desperately Needed!!

I am in desperate need of a beta to help me proofread my latest story.  Does anyone know where I can find a beta (either a site or somewhere on DW/LJ where beta's lurk) or if anyone is willing to beta a story that exploded on me?  If it matters, the story is a crossover/fusion between Supernatural and How to Train Your Dragon.  I know, weird crossover but most days that's how my mind words.
