Rotating Testimonials Widget for sidebar

Hi.

Please look at the sidebar at http://dmphoto.staging.wpengine.com/

Do you guys offer a widget or plugint hat woudl allow me to place testimonials in the sidebar that would rotate/alternate so that one showed for a few secons and then was replaced with the next one etc etc?

If not could you recommend a good widget?

Tnx

Dermot

P.S. DO I need to ask you to mark these posts private os they don't appear in google search later on?
