In addition to the regular part-time workers, it might be useful to offer a short- or medium-term residency worker program. It seems like the part-time work program you have would pretty much be limited to people who were already close.
I'd be much more interested in coming in for 2-3 weeks of more intensive work. (Especially if that could happen in the periods when it's winter here in MN and not there, like, say, now.)
