Shark fishing - Destin

I'll be vacationing in Destin in a few weeks and have this (stupid, I'm sure)
idea of chartering a boat to fish for shark, or other impressive mountable sea
creature. I've never fished for anything larger than bass before and will have
less than a full day to indulge this fantasy. I would appreciate any
information/advice from how to pick a reputable charter service to whether the
Destin area offers this kind of fishing. I'm afraid that I might be dreaming of
a multi-day, deep sea expedition which I just can't schedule, and if so I guess
I need to be told so.

Thanks,
Mark
