Date Picker and Daytime for Virtuemart 2.0 in Products

Hi all, I need a date picker in my Products from virtuemar 2.0 like a Java Popup calendar and a dropdown menu for time of day. My customers have to choose a delivery date an a pick-up date and both with the option of morning or afternoon. Also there must be a blocker between delivery date and order of 48 hours and no delivery or pick-up on saturday or sunday. I thought it would be able to put this in every product with an Javascrip Popup Calendar or something like this. The daytime can be a dropdown list with morning or afternoon. These infos have to be saved in the shopping cart and the confirmation email for me and my customers. All this fields need to be mandatory fields. Sorry for my english! Thx and I hope there is a way to develope this.
