Man, if you got the same message from me several times, my apologies. My computer's being weird as shit, and I don't know if it posted, didn't post, posted and disappeared, etc. Terrible.
That sounds like a really cool job, though. I've been looking into hospital work here in London, and I think hospitals work a little differently here, because it's hard (read: near-impossible) to find non-professional work available.
I'm still digging, but I really don't think there's much availability for anything at hospitals unless you've graduated university, or at least have some professional experience.
