Policy maps on port-channel sub-interfaces

We're trying to implement an enterprise QoS policy and I'm wondering how we can apply our QoS policy maps to several different sub-interfaces on a port-channel. In our case, we have both LAN and WAN connections that connect as VLANs on a switch and terminate as sub-interfaces on a port-channel that combines two Gigabit Ethernet interfaces on our router. The LAN connection will need to have a ingress service-policy to classify traffic as it comes from a customer LAN, and the WAN connections will have to have an egress service-policy to place the traffic classes into LLQ and CBWFQ queues as it leaves the router. Could I put both the ingress and egress service-policies on the physical router interface, or should I put them on the port-channel interface? Or should I apply them to the individual sub-interfaces? For example, I could put the ingress classification service-policy on the LAN sub-interface connection.

Any thoughts or insight would be helpful. Thanks.
