How can I get netflow statistics from cisco 3750 and 3560 switches?

Is there an official or unofficial way, maybe a workaround?

Perhaps I need a certain version of software on the switches?

The devices you mention do not support NetFlow.

This is not meant to be outright bashing, but Cisco will never add this feature. They want you to buy MARS an/or huge overy expensive chassis based switches, I see more features disappear with every ios release for the workgroup level switches. They won't even do GVRP anymore.
I have suggestions, but it is kind of off topic for the thread.

You could use a span port and a netflow probe
