Outlook 2007 Field Chooser Script VBA to Display Part of a Message in Column

We need one of the columns in the main view in Outlook (2007) to display part of the email message.

Outlook provides the field for 'Message' already but we need 'Part of a Message'. The Freelancer chosen must be able to communicate via messaging on SKYPE
