Friend,
The 3560 does not support service-policy in the outbound direction.
IF you want to configure it in the inbound direction, you can do something like this
ip access-list extended http
permit tcp any any eq http
policy-map child-policy
class VoIP
priority 128
class http
police cir 256000 conform-action-transmit exceed-action-drop
policy-map parent-policy
class class-default
shape average 512000
service-policy child-policy
class-map match-all VoiP
Match ip dscp EF
class-map match-all http
match access group name http
interface
service-policy input parent-policy
More configuration options on this link
