Calendar Website Needed (1669595)

I have a need for a website creation. This is what it will entail. The user will have to register. When the user registers they get their own email address via this site. So it might be joe@thissite.net. The user will be able to create calendar feeds they can subscribe to. Should be compatible with Outlook & iCal formats. The user should also be able to share their calendar feed link for others to view. Now here is where the neat part comes in. The point behind the email creation, is the user can send an email with specific text items in it and it will auto add a calendar entry to the subscribed calendar for this particular user. So we will need the website to auto recognize certain criteria like Event, Time, Date, Location, Reminder...etc...etc...to add to the calendar entry. So the user sends that individual items in and it auto adds them to the calendar. The email might look as follows... Event: Dad's Birthday Party Location: 2323 Main Street Time: 12:00 PM Date: 10/02/11 Reminder: 15 Mins There also needs to be a built in Trial period. So the users have 10 days to try and then after that point they will need to subscribe to the annual price structure.
