Wood Sources in U.S. for strip planking

Looking for contacts, low or cheap prices, and any buying information for WRC, Paulownia, or other light-weight wood for strip planking. I need a source who can get it to me here in central Illinois.

I have quotes at $2.50 bd ft for WRC VG-C. I think it should be more at $2.00 or less.

Anybody else know of a good supplier?

Thanks

 

There is Northern white cedar available locally. It is very light.
