Columns Plugin Problem

Hi:

My website is http://www.amaengineering.com/wordpresswebsite and I’m using the theme Twenty Ten 1.1.

I want to use a columns feature on one of my pages titled “Services Offered.”

I’ve tried the following plugins:
– Magazine Columns
– WP Columnize
– WP Post Columns

And followed the directions word for word, but none of them work on my site.

Any help would be really appreciated!!
