Anybody know places that are likely to give donations?

So i'm part of a volunteer group called Amigos de las Am�ricas. We're a non-profit organization, but we need to raise money. We're having a raffle off to give away things. We're trying to get donations from places, like clothes from clothing stores, etc. What places are generous about these things? Oh and if anybody knows of successful fundraising ideas, please let me know :))
