We need a delivery date and time picker at the checkout page of virtuemart 2.0. So this should be a shipping plugin kind of option. Should be like a Java Popup calendar and a dropdown menu for time of day (morning, afternoon or between 08:00 and 15:00).
Also there must be a blocker between delivery date and order of 48 hours and no delivery or pick-up on saturday or sunday.
These info need to be saved in the shopping cart and the confirmation email for me and my customers.
All this fields need to be mandatory fields.
