I'd be interested in this as well. The tone of the story you've shared speaks to me, makes me think this'll have plenty of room for intrigue and/or physical conflict.
From the options presented, I lean towards playing a bartender. And because I usually try to be versatile, I try to have my characters take on multiple responsibilities. Would a bartender/hunter be acceptable? I figure it'd make for an attractive hire for the owner to have a part-timer who could provide additional food (and protection, if hunters are allowed personal weapons) to the table.
