Date in custom fields

[kolmao]

I have a rental site and I need the buyer to enter the date for the reservation. I am now using the VM Custom - Customer text input plugin in custom fields, but I would like a calendar to appear instead of having to write the date and mark the day and this date appears on the invoice.

Thank you in advance for your help.
