renting company

so i was thinking the other day that it would be so great if at the end of the wedding when people left there was a pretzel oven warmer station with those big pretzels and people could take one for the road (or a kettle popcorn maker) the ones you see at the mall or at a baseball game
i keep searching for rental companies but they are all out of state
does any one know any rental companys that can do this on LI?
