Event Listing Script

I need a event listing script. It must have the following: Looking for a ready made script if you have any. Send demo URL if you have it. Three sections; Admin: 1) publish/unpublish events 2) View/Delete/Edit events 3) Activate or Disactivate events 4) View/edit/Delete registered users 5) change admin password User: 1) Must register with site thru a return email 2) use email address and password to login 3) Allow to post/edit/delete their own events 4) Allow multiple event postings 5) Allow to copy their existing event 6) publish/unpublish events(default is publish) Browser view: Events listed in descending order If the date for the event has passed already then not shown. This gives you the basics of the script. Would prefer a ready made script. Max budget $75 Needed ASAP and must be available on msn most of the time.
