Need to host a contest with video/audio submissions

I am looking for the absolute easiest way to do the following:

Offer a contest to find the best video submission when reading a script provided, with the goal of imitating a certain unnamed famous actor, when reading the script. People can submit an audio if they prefer.

There will be three awards:
1) Most like this this specific famous actor
2) Most original
3) Most comic


The judges will be the people and there will we be no "committee". Instead, the date and time of the final decision will be posted up front and whoever is in the lead of these for each category at the moment, are the winners.

Does Facebook allow this? I hope it does.

if not, what options are there? I have a WordPress site. Any plug-ins that support this?

Thanks
