I am selling a used Lakeside stainless cart.  The wheels could used being scrubbed with steel wool but the unit is in great shape.  These retail for ~$2000.
To provide mobility, the Lakeside 733 Queen Mary cart is equipped
with four 5-inch casters, two of which swivel to increase
maneuverability. Its push handle helps users guide the cart, and the
flat shelf edges facilitate loading and unloading. Durable to support
heavy-duty use, it’s made of rust- and corrosion-resistant stainless
steel. In total, this unit can hold 700 pounds.
