Saturday farmers market in Brownwood there is a butcher that come usually parks by blue fin. Meat is excellent, I am sure they would be happy to accommodate you. Name escapes me right now, but have bought from them several times.
You mentioned boneless would work, but it would no longer be a standing rib roast. Just roast.
I sous vide my standing rib, to rare, then torch the outside to get that crust a standing rib should have.
