General information for the website: sales page for http://nationaldiversified.co.uk/services/products/to-business-owners/
Num. of web pages/modules: 1
Description of every page/module: I need a shopping cart payment option written for my webpage

The payment option is in the form of a table to the same style as this website (seen near the bottom of page)

It allows a person to choose between one two product choices inside a table
