Looking for a suggestion: Need plugin/widget to scroll client's testimonials

Hello all..

I’m looking to have an area, hopefully customizable width, where it displays client’s testimonials in a quote fashion. I’d like a new quote to appear every x amount of seconds.

I’ve seen plugins that do a slide show of images and I’ve seen widgets that display random quotes (every time the page loads) but not one that does it in a slide show fashion.

I appreciate any suggestions for plugins or coding,

Thanks!
