I'm looking for recommendations for mail-order labs in USA for processing 120 color films. Want the roll returned un-cut, no prints, 6x12 format. I will be (shhhh) scanning on 3200 flatbed and then printing.

Does anyone use the Kodak or A&I mailers for 120, I would imagine they would do this? I don't want the returned cut up in 6x6 mounts, for example...I used to use "The Lab" in St. Louis years ago for 120 format, but couldn't find them online. Have good labs here in Seattle, but mail-order is way more convenient for me.
