Routing multiple VLAN's on a LAN

I am planning a solution for a multi-tenant office building. There are Catalyst layer 2 managed switches in place. They want to give about 40 separate businesses their own access to the 50Mbps internet pipe but isolate each one's traffic. I'd like to accomplish this with a router or firewall. I'm thinking of using a 1941 with multiple VLAN's and subinterfaces, and also use the router to handle DHCP for these multiple subnets. Is it a reasonable solution in terms of performance and configuration, or should I choose another model.

Choose another model - check numbers, 1941 is not good enough for what you are planning to do.

It seems a layer 3 switch will be a better solution for this.

Yes, way much more better. But if you are planning to do natting for everyone you'll need good firewall too. Also, if you are hosting 40 companies and sign SLA with them you will also want to have high availability. That would mean that you should have at least 2 decent L3 switches (at least that would be my plan). Also, QoS should be included in design.
