Car washes! Sell tickets in advance. Tickets will be valid for one of two Saturdays in a row. Most gas stations will let you use their lots and water for free.

Have class or team competitions to spur the sales. Students and parents (fathers especially) will give up 2 hours on a Saturday to help out.

You will pre-sell a lot of tickets, but don’t worry as they won’t all show up. Many who buy do so just as a donation, get busy, or just forget about the date.

I have done this myself with middle school students. Don’t be surprised with the easiness of set up, follow through, and pure profit.

if the stuff that is left donate to a local charity
