30 hours a month will take some doing. I'm in a group of 8, and we don't do that collectivly.
My record is 300 hours in a year, and that was flying at EVERY opportunity going. Aint easy or cheap.
Another angle you need to get covered is the maintenance, not only the when (and not forgetting where), but if it goes in for an annual and there is a problem, what happens to your 30 hour requirement?
