Spacing at the bottom of each page

I would like to minimize the space at the bottom of each page. In the link provided, under the logos from all the other tool companies at the bottom of the page there is a large white space. I would like to minimize that area on all pages so that the final content sits close to the bottom, but not exactly on it.

Thanks for all the help.
