What is the duration of this project? Is it to set up systems over one year and then maintain/apply/monitor them afterwards?
Perhaps one other alternative is to hire a series of ambitious men on slightly overlapping contracts who are early in their career and are looking to eventually get into similar/related work. They would have an incentive to learn as much as possible during their stint, as well as perform well and maintain good attendance/not cause drama to stay in the good books with yourself and partners for their own future sake. The time bound nature of this would also mitigate the getting bored aspect, as after they've had a good learning experience and given reasonable performance, they'd be just have to train their replacement and be onto the next stage of their career, whatever/whatever that is.
