Ways to raise money for my sick horse? Please help...?

My horse is colicing really bad. He's in the Equine Specialty Hospital right now but he may need surgery. We aren't sure what he has right now but if he does need it, the surgery is somewhere from $10,000-$15,000. My parents have already paid over $1,000 just tonight for boarding and the treatments and they said that they can't pay for that surgery. Is there any way that you guys can think of that maybe I could raise money....like A TON of money within like 2 days! I know thats crazy but Ollie is the love of my life and if he dies then I die....no if ands or buts. No joke though...you may think I'm over exaggerating, but I'm not. Ollie is my everything and I can't stand to lose him...thanks.
