Wireshark will show all connections, packet details, protocols, everything. Don't know about loads.http://www.wireshark.org/download.html
Do those 30 computers have desktop firewalls, antispyware, antivirus installed, updated, and running all the time and users are prevented from fiddling with the settings, and is IE setup tightly and also prevented from being changed by users? If the answer to any of this is 'no', the boss will pay more in the long run for data lost or stolen and for the need to fix broken computers all the time.
