iCal or Entourage do this?

[AMDin93103]

I use iCal (1.5.5) currently but own Entourage (11.2.1) as well. I have clients that I service on a weekly or biweekly basis whose appointments are in iCal; I call and remind them the day before. The majority of these people are great about checking email. I would like to set up an automated email reminder which is sent to them for each appointment, two days in advance that does not contain an .ics file. Many times my clients' email app has junked the message due to the small attachment. Others don't want to open a file when they don't know what it is.

FWIW, I don't know AppleScripting or any coding for that matter. Plug-ins and ready made solutions are always fantastic The request above would greatly simplify my evenings spent contacting clients. Please help! TIA.
