Through a google search I was able to find help on how to make a basic pricing table (not as spiffy as the ones above) from a site called coveloping.
You create your price table using their generator (http://coveloping.com/tools/pricing-tables) and then paste the CSS code in the custom css section of the style editor. You then take the html code they provide and drop that in a code box on any page that you want the pricing table to appear. You'll need both codes for this to work. They explain how to do this here: https://coveloping.com/embed-pricing-table-squarespace-site
For an example of a simple pricing table that I made you can check out our site here: http://www.j-and-m.org/social-media-management Hope this helps.
