Hello,
This service does not exist. I'll try to explain it, but English is not my native language so it can be hard to understand.
When you sell your btc, the provider gets a order from you. It takes time to review your order, then they send you your money. But only if you are using the same bank as the provider, you have a chance to get the money in a few hours (depending on the bank times). If you have another bank account as the provider in the same country, most likely you will get your money in one working day. If the provider is in a other country, it usally takes 3 to 7 working day's.
What i'm trying to say... It's a banking thing and not a providers thing.
