Natural Birth Options, Memphis Area HELP!

I am wanting to do natural birth. I love my OBYN though! I haven't spoken with him yet about this. So I am not sure how he stands on it. Does anyone have any suggestions for doulas in the Memphis, TN area or North Mississippi? Has anyone had great experiences with OBYGN and doula combination during pregnancy and labor? Do you have any suggestions? Are there any great Midwife/Doula Pregnancy Centers in the Memphis, TN or North Mississippi Area?

Thanks! Any information would be appreiciated. I am new at this!
