3 minute presentation need help urgently

hello i'm michael i have a 3 minute presentation on saturday which could be the most important of my life. It is entitled "Why I am interested in a career in business to business sales and why I think I am suitable." I have read through the site and have a few ideas but don't know how to structure them, I want to stand out from the other 30 or so presentations that the observers will see that day. I can't use a computer only flip charts and a projector, so I have drawn a cartoon depicting a person giving a boring presentation to grab their attention at the start, where do iI go from here.

Any help would be greatly appreciated as I want to get this done tonight so I can practice it tomorrow and friday.

Michael

Personally I would use an example of something that you have sold. If you can define,
what their problem was
what the solution was that you enabled for them, and
how excited you both were with the result
could work very nicely.

The key is to be brimming with enthusiasm.

Good luck.
