I would create a charity raffle. 30 tickets costing BTC0.05 each. BTC1 to the charity, BTC0.25 to the winner and BTC0.25 to transfer fees and grow the pot for next raffle. This can be tweaked as the pot grows or prices change dramatically.
The charity (chosen by the winner) would need to be one recognised by a state or federal authority.

To guard theft or scamming, a second person would hold the key for second authentication of the raffle wallet enabling transactions.

Due to the pot growing, we could also offer a booby prize to people that have played 10 times and not won.
Details of raffle would be transparent to ensure accountability.

An example, $130 can support a child's education for a year http://www.balischoolkids.org/about
