Fundraiser Ideas

It is getting closer to the time where I am putting my thinking cap on for fundraiser ideas to get to Mexico for the mission trip to the orphanage.  We have a local pizza place that will allow us to bus tables a night for tips and a local grocery store that lets us hand out coupons for a day that give us a percentage of sales.  I am glad to have those opportunities but I am not sure they will be enough.  So I am reaching out to my readership for some fundraiser ideas.  I would appreciate any comments you can leave with an idea!
