We are currently looking for miners as have a 4BTC backlog!
We pay equivalent to 1.2 million difficulty.
https://bitcoinvanity.appspot.com/sp/minerhelpPlease note that this is very high variance - we just pay for found addresses - is more like solo mining for a 2BTC payment at the moment.
Also note that this is quite rare that we have such high difficulty addresses to find. Normally our in-house GPUs are sufficient to meet demand.
Remember to get oclgenvanity.exe to run you often need old GPU drivers.
