Hi, can anyone suggest a solution for this please?

As part of our crypto project MonetaryUnit https://bitcointalk.org/index.php?topic=778322
we have in the past ran a "lottery" type game, which was all manually done and pretty time consuming, you can see the simple site here www.BitcoinPrizeDraw.com

Ideally we want to automate/semi-automate it so we can resurrect it and also make it at least cost neutral, but hopefully generate some revenue which can be put into buy support for MUE, so any suggestions welcome.

Thanks
