@ SailorJerry - First of all, congratulations on your impending fatherhood! What an exciting time for your and your wife.
You'll want to tour each hospital, but keep in mind that what you see isn't always what you get. A hospital might draw people in with a jacuzzi tub that hardly ever actually gets used. And having squat bars on the beds doesn't mean that the nurses will be supporting of your birthing plan.
Word of mouth is the only way to go. A good place to start might be for your wife to attend a local La Leche League meeting. While the focus of the group is breastfeeding, many members have an interest in natural childbirth and may have stories to share.
Finding the right provider is also critical. Once you find the right person and the right place, you can always bring your own birthing stool if they don't have them--ask your provider first.
