Smoothie Maker

I'm looking for a smoothie maker to meet my business needs. Specifically, I'd like to make large batches of smoothies, serving 5 or more people at a time. The type of smoothie I'm looking for is fruit-based.I need a smoothie maker that can handle a sustained and significant volume of servings with consistent quality and minimal downtime between batches. If you have experience making commercial-grade smoothies , I'd like to hear from you.
