Our current publication project is a book for the high holy days. In addition to distributing online as with our past books, we'd like to also distribute physical copies. This is an opportunity to spread torah from Mi Yodeya to (parts of) the broader Jewish community.
To do this, we need to print books. Hundreds of books.
We did some estimating and some research, and we1 believe we can print and distribute 500 copies of a 50-page book (that's similar to the haggadah supplement) for about $1500. If the book is a little longer or a little shorter, or we need fewer or more copies, this number will change, but this is a good baseline. We can do a lot of good in the Jewish world with 500 copies of a 50-page book.
We approached Stack Exchange to see if they could help us with this, and came back with the following proposal: Stack Exchange is willing to match our fundraising 2:1, up to $1000 from them, to publish this book. I can't over-emphasize how wonderful this is; Stack Exchange has pretty much stopped doing special site-specific projects like contests and convention promotions, but they're interested in helping us on this because we have a great track record.
Can we raise at least $500, quickly? I think we can.
There are at least two options that have come up in chat, and maybe more we haven't thought of. In answers to this question please propose an approach (one per answer). Please also address what would happen should we raise too little or too much money (hey, it could happen).
Please also bear in mind that whatever we do needs to be done in the next few weeks. We'll need to commit to a print run by August 13 in order to have copies in synagogues in time for Rosh Hashana.
