I wouldn't worry to much about not having field experience I dont think that is particularly unusual. Nor do I think being from outside the discipline is a big deal. I have a BA in Anthro and I didn't receive any esoteric preparations for fieldwork--no charms, no incantations, nothing. I cant even remember if I took a methods course. I don't have a traditional fieldwork experience in exotic locals. However, I've done a significant amount of social movement research and work in community radio which amounts to a buttload of interviewing experience. I also work in the field I want to study--livestock agriculture in the US. Some fieldwork experience is better than none. Do you have other experiences and skills that you could tie into your proposed fieldwork? A language? Recording and editing experience?
