Thanks for all of the information folks. I believe in hindsight this is what is called a clusterf*ck. Perhaps, next time it would be better to go after a convention center or another venue that can handle these kinds of numbers. Of course, you've got to be able to predict the kind of numbers ahead of time as not to waste too many funds paying for a large venue when only a few will turn out. Honestly, with the volunteer/voter ratio being as low as it was I'm somewhat impressed that it went as smoothly as it did. It could have been worse. 
Seriously though...ballots.
