A question about lemonade?

am going to have a lemonade sale on Saturday. I bought the "Old Times" Pink lemonade powder, I bought two so I can have four jugs. If I am correct, the box says it contains 8quarts of powder, 4 quarts equal 1 gallon, which is about 1 jug of lemonade, so yeah. I am going to buy cups, i made a poster, what else do I need, except jugs, a table and a chair, a money box, anything else..? ANY TIPS>>?
