It sounds like you're not interested in relocating to go to school, but, if you know you want to pursue nurse midwifery, I wonder if you've considered the direct entry Master's programs? They take people who have a baccalaureate degree in something else (but I'm sure they wouldn't hold your Master's against you! :chuckle ), you do one year of basic nursing and then go right into the MSN program.
Since you asked for advice, I would encourage you strongly not to limit yourself to options that don't require you to give up your day job or move. This is the rest of your life you're talking about! If there is a program somewhere else that really interests you, I would encourage you strongly to pick up and go there and do it. Student loans and scholarships
are plentiful (esp. for nursing) and repayment is relatively painless. Also, there are some programs that allow you to "work off" the loans instead of paying them back. Whatever
path you choose, it's going to require a lot of blood, sweat, and tears (and $$$$) -- you might as well have the education and degree you really want when you're done. SCHOOL IS (comparatively) SHORT -- LIFE IS LONG!!
Best wishes with whatever you decide --
