Need some ideas! Not wedding related!

I have a couple things.. I'm my FI's Troop FRG Treasurer. Basically I was just a name to fill the volunteer spot and never did anything in the past year. The new commander is super involved and really wanting to do a lot of fundraising. I'm trying to brainstorm and come up with some unique fundraising ideas. We're doing bake sales and carwashes, garage sales, etc. I was wondering if any of you have any ideas. I'm a photographer and thought of doing family pics for families on post as a fundraiser. Good idea?! Also, for the ball this year there's a centerpiece competition. Each troop has to come up witn 3 creative centerpiece ideas. So I'm trying to brainstorm for that. So yeah, throw out some suggestions. Lol . I'm so not creative.
