You should take your technology and apply it to the nursing industry. I've been saying it for years: Healthcare is an inefficient marketplace. Hospitals always have a hard time filling nursing demand, so they go to extraordinary lengths. For instance, we currently live in Portland, OR rent free while my wife makes more than she would if she lived here, all because they don't have enough nurses. My wife has a recruiter, who sends her loads of paperwork.
There's totally a startup that could make a lot of money. Maybe start out as software for recruiters to manage their "inventory" of nurses? Then expand into a full on marketplace, eventually disinter-mediating said agencies.
