need advise please, Lots of traffic

[areav]

Hi I have a site that will get a huge amount of traffic tomorrow. Probably around 20,000 hits. As of now the site does not even have anything on it.

My question is: besides a little of my content, what should I put on the site as far as pay per click (Adsence, etc)

What is the best and will it let me do it in one day?

thanks for the help.

Jude.
