Without knowing from first-hand experience, I would surmise that there are probably a few, but not much more than that. There are some local businesses here for certain, and some may be looking for help, but within Haviland itself, probably not many. Retail and restaurant opportunities are pretty limited.
Another option might be something along the lines of babysitting, and I see no reason why there wouldn't be a need for it here. There are families living in town, which would make that a more viable choice. Still, I can't imagine that there are a ton of opportunities here for kids, but that's just my read on the situation.
