How do we limit bandwidth per port on a Cisco router, and which models will do the job?

We have a requirement to supply a leased line to a building which has two separate departments - and they want to limit the maximum bandwidth one of the departments can use to, say, 8Mb/s. Assuming one ethernet port for each department, what's the least expensive model of Cisco router that will do the job properly, and what commands would we use to configure this?

Thanks

Just about any Cisco router will handle this.

You set the maximum rate per-port on a Cisco using the "rate-limit" command; you can rate-limit inbound, outbound, or both.

Would it need to be a router with QOS available in the IOS image?

The project has changed slightly now, so we won't get to actually try this for real - at least not yet - but I'm going to hand out the points now anyway.  Thanks for the advice.
