Hey there girl. How are you? There is alot to do!!!! I have been doing live/silent auctions now for DD's schools for the past 12 years. And we always start almost a year in advance with solicitations. My opinion is live makes more $$. There is an auctioneer here in the state that does school fundraisers. And he donates his services. Here's a few more ideas that I haven't seen posted yet.
Have parents donate a party for an entire class. Pizza, Ice Cream, movie breakfast. These go for huge $$ because the class parents can all chip in together to win this. These parties have never sold for less then $4-500.00.
dinner with the principle
dinner with the Mayor
a ride to school on a fire truck big $$$
front row seats for all events: k graduation, plays, etc. we did the same for Church events because my DD went to Catholic school. First Holy Communion, Christmas Mass, Easter Mass etc.
Weekend get-a-ways. Try to a put hotel, rest gc, and entertainment together. Bigger package means bigger $.
Send me a PM or call me.(do you still have my #). I can try and help you with instate places I know will donate.
