How much does it generally cost to put down wood flooring?

Question:Just the labor part; how much does it generally cost to install wood flooring? Not laminate, solid wood floors. Materials not included, just the labor.
Oh, BTW...for a space that is about 700 Sq. Ft.
Thanks!

Answers:
It depends. I have had people charge anywhere from $50 to $100 an hour labor. It is the labor that usually costs you, but if you want it done right it is worth it.
