Natural Birth

My mind is definitely made up to have an at home water birth with a certified midwife. My husband is on board and I'm at peace with the decisions. My mom had 7 children, all of us naturally. She hates going to the hospital because they would pressure her to take all these medications or schedule a cesarean. With one of her pregnancies, my dad missed one appointment with her & her Dr tried to pressure her to sign papers to have a cesarean. When she refused the Dr told her the baby was too big she wouldn't be able to push him out. She never gave in to the pressure & had all of us naturally. It'll always made me cringe about having my children at the hospital. I know not all hospital birth is a bad experience but I always knew I wanted something different for myself. We just finished watching "The Business of Being Born" on Netflix. It was so informative & influential on our final decision. I need help to find a certified experience midwife. Like, what's the next step? Where do I begin? Should I do my own research or ask my gynecologist?
