I build rods and have to tell you, that question is far to vague to give you any kind of figure. Which blank? What reel seat do you have in mind? Do you want a plain grip that was pre-made or do you want something a bit flashier turned by the rod maker? What kind of guides do you want on the rod? Do you want a feather inlay or some type of thread art on the rod? With what you have in the question, the only answer you can get is like the one JP gave you. The name of a fair priced builder, but not what you should expect to pay.
