I don't understand the role of a vpn here.  Normally you would split address 
ranges and use firewalling (iptables on linux, access control lists on a cisco) 
on the interfaces where they connect.  So your 3 companies would simply be split 
into different subnets with routing between them blocked on the device where 
they connect.  A VPN is used if you need to connect things through a firewall 
that would otherwise block it - you might use that for your administrative 
access through the firewalls of for portions of companies in remote locations.
