Any arrangement of this kind is likely to require a balancing commitment on your part, though. You, and probably your senior students, should plan on making that 45 minute drive on a very regular basis. (Incidentally, plenty of people do not see a 45 minute drive to a good dojo as particularly onerous. )
That's about my daily dojo commute. Sure would be nice if the dojo were right down the road, but it isn't. In fact, when I was living a lot closer to my (then) dojo, it still took about 45 minutes because it was by public transit.
