Most people will charge you around $4.50/foot to install. Could be more. To me something like that is worth it if you don't know what you're doing. A wood floor is an investment that pays big dividends!!
I just had an exotic wood called Kempas (from China) install and man, it looks awesome! You should check it out. The colors vary and give a neat, classy look without the expense. Most woods like this cost $8/foot or more. Lowes has it now for $4.58/foot. Here's a picture of it at this link:

This word is solid and very hard. They finish it like all the other stuff.
