Hello? no one??!! :)

Try the "building a home" or "metalworking" forums. you might have better luck getting a response :).

There are basically three types of stairs for homes: carpenter built, custom built, or manufactured. The former two are what I see 99.99% of the time.
For custom stairs, the shops that you will have bid on your plan usually have a snall showroom in front of their shop and have samples of various stair parts put together.
If you do carpenter built stairs, then that leaves only the railing and balusters/newel posts (the ballustrade) to finish.
In the past few years, wooden newel posts and railings with wrought iron ballusters has proven to be a popular combination. I ordered cherry railing and metal ballusters plus some installation tools from stairpartsusa and it worked out fine.
