Is this still a thing? E-mail sent through contact form a few days ago still unanswered and the statuses are showing unpaid, but they have been. Just trying to figure out if I'm being too impatient or if something is messed up...
There's an alternative (a pool) running (I mine on it and just created an address yesterday for one of its customers):
https://vanitypool.appspot.com/.
It's cheaper (and the recommended fees are even a bit overvalued: my miners don't pickup work from this pool unless it's more profitable than mining Bitcoin or Litecoin. With the current mining market conditions, they work on 7 char address prefixes (including leading 1) if they are paid 0.05BTC or more. Bitcoinvanity asks 0.84BTC for the same service...
If you look for several addresses using the same public key you will make it even more profitable for miners to work on them and could lower your fee a bit for each address.
