Simple date availability widget in iWeb

I can integrate my iCal calendar to my iWeb website using the HTML Snippet tool in iWeb but this shows my entire itinerary. I want a very simple calendar that the visitor to my website can click to see if I am available or booked and that is it, I want this to be linked with my iCal canender if possible. The calendar is also published on MobileMe. I think I would need some fancy HTML script for this but simply have not got the tech know how to accomplish this. Can anyone in the Mac community help me out.?
