Well, I guess my name says it all.......
Don't have experience with stainless props, just aluminum, but I'd recommend Tacoma Propellers in Tacoma Washington.

Last year was our first year boating, and I managed to chew up two aluminum props. After the first one I found Tacoma Propellers on the web. Their price was the best I could find and I bought a new prop from them, then proceeded to grind that one up a couple of weeks later. Decided rebuilding was the way to go. Especially after my trusty navigator, the vivacious Rag Top Daze, threatened to start displaying the broken props on the front porch, using them as flower pots!
They redid both props For $120 which included the return UPS ground shipping. They were friendly and easy to work with and did an excellent job on the props and shipped them back quickly.
They are over on the other side of the earth, but I'd use them again, although my navigator's skills do seem to be improving!
Good luck!
