Sell annuals and perennials in the spring, hold yard-sales in the summer, bake sales in the fall, and sell Christmas wreaths in the winter. The work is rewarding and the cash immediate. When you hold a yard-sale, everyone on the team can pitch in, bringing their old or unwanted items to a central location. Remember that cupcakes and cookies should be sold separately, as they are easy, quick one-person snacks, and will sell for more money individually. Organize a lemonade stand as well.
People enjoy yard-sales, and helping out, especially when the cause is for children.
Christmas wreaths are easy to sell. Nearly everyone hangs a wreath on their door during the holidays, so there is always a big demand. Find someone on your team or committee who has evergreen trees in their backyard, or purchase a couple of bundles of greens. Purchase wire at the local hardware store. The wire will be used to wrap the individual fist size bundles of greens to the ring.
