Install a Wordpress sidebar plugin (ww)

We have a brand new Wordpress site which has one working sidebar on it: [login to view URL] The sidebar that is currently displayed shows only sub pages of the 'Club Facilities' page. And these are not shown in the main navigation. This is perfect. However we need a new sidebar also above this one, styled in the same way with the title 'Find Out More'. This simply needs to display sub pages of whatever page we are currently on. So, for example, if we are on the Membership page, we would want to see all sub pages of Membership only. I will give full access to the winning bidder, including WP login details, ftp and Cpanel access.
