Places that will dry wood for luthier-related use?

I live near Saginaw, MI. I have a couple of pieces of ash that I would like to have preferably kiln-dried. I have tried self serve lumber and they said they don't do that for customers. So, anybody that live in saginaw that can direct me to a place to get these suckers dried so I can get to building the body of my 8 string guitar?
