Sherwin Williams. Click the link to go to the store locator.
I called the one closest to my house. The lady said that I could bring a sample of wood, and what I wanted to match to the store. She said that they generally need to keep the object you are matching, and the wood samples for a day so that they can ensure a good match. You may need to get Axiom to send you a small scrap of boston cherry vinyl. Unless you want to leave a QS8 with them overnight. They will mix, and let you look at the resulting stain on your wood samples before you buy it. They can mix stains for every type of wood.
Disclaimer: I have never used their stain, or had them mix any for me. I have a guy working for me that used to be a carpenter. He told me about Sherwin Williams' stains while I was discussing the trim in my house with him. I trust him, and he said they were excellent stains, and that they always did great with the color matching for him.
