Crank Shops for Offset Crank Grinding?

Wanting to see if any of you guys know of a shop that can offset grind cranks, re-harden and balance. Mid-Atlantic preferred but can ship to a good shop. Not for Mopar..... Opel 4 cylinder 1.9L forged crank. I plan to offset grind the rod journal to move center outward by .125", for .250" longer stroke. Tnx!
