I can't say I have much of a taste for it anymore, when I returned to London the first thing I did (quite literally) was get a Butterbeer.
I would consider it, I'd just be afraid of the business failing.
I mostly learned from Minerva McGonagall, but yes, there are instructors of a sort. It's really not something you can do on your own, actually. Doing the transformation incorrectly can result in permanent damage. I suppose that's something to look into.
