Our school district has a committee called "Ways and Means" and I think they are the ones who handle fundraisers....probably can contact them through the PTO as was previously mentioned. Most school districts have websites now too and you can get names, phone #s and email addresses of Booster Clubs, etc. without having to hassle the "gatekeeper"!
Find out some info on soccer clubs, little league, swim teams, etc. for next spring, too!
