May I ask what kind of organization this is? Is it for shelter cats, abused women, the environment or something else?
We're a university organization oriented to those in a particular major or field of research. Two of our members were in a terrible accident this weekend and we're trying to raise money for bills, etc.
I'm so sorry to hear about this. I'm hoping the two will be okay, in time, and will be able to come back to your group. You and the other members are very kind in trying to raise money for such a cause.
There's always the standard "A fund has been set up at Xbank if you care to donate to the cause" type of thing that you can send out with newsletters, maybe a polite request via personal e-mail, post fliers on the doors of the research building, etc.
Print up a bunch of 1/4 page "business card" types of leaflets (8-1/2 x 11 regular paper, cut in fourths) with Cause for donation, Xbank fund info, along with a "Thank You" . . . that you can give to other organization members so that when they are asked "Is there anything I can do?" it would be easy enough for them to hand over this leaflet of info and respond "This is what we're doing. If you can help, it would be appreciated." No hassle, no muss.
Whatever you do, I think that an account should be set up at a bank for this type of fundraiser. Probably don't need to tell you, but keep careful records.
Along the lines of Outdoor Girl's suggestions, are there any students that you can reach out to? Get their thoughts and involve them with planning such a fund raiser?
