Does anyone know some good Fund-raisers?

So I'm a captain on our Flag Corp (Color Guard) and we will be attending a big trip to Florida next spring to perform in many places. We also need to raise money for future uniforms (We've had ours for 3 years now) and new silks plus other equipment. Our captains this year are in charge of coming up with money makers that the whole corp AND our Director will love. I've thought of the basics such as car washes, Bake sales, and rummage sales... If anyone can give me some more ideas or some stats on how well these fundraisers worked so I can support my ideas, please do so. Thanks =) *Our Guard consists or 14 flags, and 3 majorettes.
