Needed: large cooler with wheels. Anyone have a spare?

Does anyone have a large cooler with wheels I can rent *for two weeks?* It is for opera singers rehearsing in a space with no air conditioning. Morale at rehearsal has been very low! The cooler will supply cold drinks, cool face packs, radishes, and other icy, opera-singer-friendly, morale-boosting treats! Need to borrow ASAP! Joy
