Add A 2nd Category Description to 2 Custom Post Types WordPress

I have 2 custom post types with their own taxonomy. I need a second description added to the category section of both custom post types. So when I go to the custom post type to add a new category, I should see a second description text area named Description 2. I have a custom page template you need to echo the description into. I will style it and position it, just load it on the page. I need this done within 1 hour. Bid is in canadian dollars. Thanks
