I've been tossing up whether or not to do this for a while now, but the more I think about it, the less reasons there seem to be not to. I have about an acre of space I could use to do this, and have access to water (property backs onto a freshwater river, which I can pump from at the price of fuel). The market price for dragons seems to stay reasonably stable, and as far as I'm aware, if I did start farming them, it would be the closest operation to the CBD.
I had the power put underground a few years ago now, and have some large telephone poles I can use as growing poles for the vines. How many tonnes I would need to produce to make it worthwhile, or the time investment involved, I've no idea.
Where should I start? Who should I be talking to?
