Here's the website for Jan Eklund http://www.jan-eklund-midwife.com/
I would honestly just set up a few interviews. There are some great questions to ask in the book Ina May's guide to childbirth (at the back).
I've talked to Dana, Jan and Jessica. It really just depends on what you're looking for, some of them I was way impressed with their website info etc, but it wasn't until I met them and spent some time with each that I was able to decide.
