what is best contact in italy through whom i can charter a private
plane in verona to fly to rome, please?

You can reserve a private charter at this website:
Flight Time
http://www.flyaow.com/privateplanes.htm

Just enter Verona as your departure city and Rome as your arrival city
and specify the dates and times.

It looks like you can also reserve a flight in Italian at this
website:
Amadeaus
http://www.amadeus.net/pl/catullo/it/avail_only.htm

I entered in your basic information and found that you will depart
from VILLAFRANCA MIL airport in/ near Verona and arrive at FIUMICINO 
(FCO) airport in/ near Rome. You can also arrange for a Limosine at
the "Flight Time" site.

Here is the homepage for the airport in Verona, with contact
information:
