Ari,
If you Google "Fundraising Quizzes" you arrive on a site with a selection of themed charity quizzes, some dowloadable and some for which you have to send an SAE. Also "Answerbank" has a Quizzes and Puzzles" section (at the start of the site in red letters) where you can see a selection of all the latest charity quizzes. Good Luck.
Just don't bring back all the "iffy" clues back onto the Crossword Forum !
