Sweet Charity may be your best bet. I think it runs twice a year and they pick different charities for each year: [link]
The main site appears to be hacked now so I'm not sure what'll happen with the next cycle, but some fantastic vidders have offered their services for sale in the past (the main organizer, Lithiumdoll, is an excellent vidder herself.)
ETA: And of course, there is Vividcon auction that happens annually. But that cycle won't come around until the beginning of next year. You don't have to be an attendee to bid on a vidder.
I believe Sweet Charity has ended.
Really? Oh, that's a shame.
Oh, the joys of fanfiction.net; where one gets comments like, "Lucy was given a dagger by Father Christmas, not a knife!"

God, Consuela, how could you make such a mistake? I'm ashamed for you.
I know. I should really just delete the whole story.
Don't stop there, erase them all and delete your user name. It's the only way to remove the shame.

You keep using thees word. I do not think eet means what you think eet means.

Oh, and now she's complaining about how long my chapters are. And she's someone without an FFN account, so I can't even reply.
It's really entertaining.
I've never understood people who don't just *stop reading*. If you don't like something, you're under no obligation to stay, and certainly not to nitpick and whine.
I opened a really promising SPN story this morning, and within paragraphs I had a windscreen and Sam talking about Dean "boxing him about the ears" so ... I closed it. It's easy!
