I had Simmons do one for me about 6 years ago and had to send it back for rework and it is still not what it should be. I can only recommend you pursue some of the other shops that have a good track record.
Jim Weigand in Indiana is the best. He does the bluing for the Winchester Master ingraver Pauline Muerle and it is the best, perfect every time and always in a very reasonable time and a very reasonable price. And when he is finished it will look like it just came out of the Winchester factory.
