How to find a midwife for home birth

There is possibility that I may lose my insurance in the next couple of months.  I would rather have an epidural and deliver at a hospital but I know that a midwife/Doula may be a more financially sound option and I am open to it. Since I'm at 22 weeks I would appreciate any suggestions on what to do or how to find a midwife for home birth online? Thank you in advance for your help.
