Add profile pages and email capability to my site

I have a website ([login to view URL]) and need for someone to create pages where users will have additional functionality for their profiles. Template pages need to be created (approximately 7 or so). I also need the capability for the users to create emails and the ability to specify the email address, time, and date the email will be sent. The need to be able to create messages which have time and date much like a blog. Also need to be able to add audio attachments to an audio upload template page stored in order by date time.
