My Dad did this when I was a kid. I was always impressed with the idea and hope to try it myself someday. From what I read of farming/agricultural articles, we need more people like you. Go for it!
For what it's worth: I had the opportunity to travel through Ukraine this summer and saw something that was pretty interesting. There were what looked like semi tractor trailer flatbeds out in fields, loaded up with probably fifty or so beehives. I've never seen that here in the states, but it seems like a neat idea. Take the hives to the crops, where it's needed, when they're ready.
Unfortunately we were on a bus and I didn't get a chance to snap a picture...
