Joe, Connect a Cisco 1912XL or 1924XL to one ethernet port on your router. Set-up one sub-interface on the ethernet port for each customer. Enable ISL on each sub-interface. CAR each sub-interface to the rate desired. On the switch you'll need to set-up a VLAN for each customer and ISL trunking on either the A or B port uplink port. You can also do this with other vendors switches using dot1q encapsulation instead of ISL. You can also enable NAT on the router and assign each customer private IP address space. One caveat, this only works for 3 or 4 sub-interfaces. Good luck.
