Help!! Need Creative Presentation Ideas

HELP HELP HELP!! In desperate need of creative ideas for a presentation that I need to give for work. It is an advertising presentation pitching a new form of advertising to the client - so the more creative the better. Trying REALLY hard not to use power point but am really struggling to come up with unique creative ideas.

Any help will be most appreciated.
Thanks

I'm a bit stuck on this one without knowing the form of advertising that you are referring to.

One suggestion si to do a day in the life of a marketing person where you can contrast the two different types of advertising that you are looking to compare.
