Create an .ics file on the fly from email link

I'm a 1shoppingcart user and I need help with this. I would like to have a client fill out the form on my website and subscribe them to an autoresponder. The autoresponder will send me a message with all of the form field info. (I already have this done). Now what I need to add is this: the email that gets sent to me has to have a link to open a webpage that will create an .ics file on the fly (so I can add it to my calendar). The .ics file that gets created would automatically add the form field data (that the client provided from the form) I'm using Microsoft exchange of my calendar. Opening calendar with my iPad/iPhone
