As a former Massachusetts banker, I know the hassles these "omnibus" subpoenas often cause. We sat with bank counsel and learned (this was 5 years ago) that there's no standard fee, and, when the subpoena (particularly a subpoena duces tecum), came from an attorney rather than the court itself, there is some negotiation room.
We always started by contacting the attorney and trying to whittle down the scope of documents. Often, we ended up providing first statement copies, and then we provided detail documents (deposit items, etc.) after the attorney had a chance to review the statements. That way we didn't spin our wheels killing trees unnecessarily. We also tried to negotiate a cost reimbursement based on our standard fees to customers for statement and item copies.
If we could not get agreement on reimbursement, and if the amount was large enough, we were often able to get the court to order payment by showing up with documents, and advising the court that we had not been paid.
