Go from door to door office to office and shop to shop asking if anyone would like to purchase Luminarias for there yards or store fronts on Christmas eve.  This is a great in expensive way to make a lot of money.  Sell the Luminarias buy the dozens.  You can give each member of your team an order form so that each member can go out and try to sell as many dozens as they can.  You will need to bulk order tea light candles and brown paper bags and also purchase a big heap of sand.  Have your team all pitch before the delivery date to fill the bags together.
