Well, friends+money can work, if you're all very serious about things from the outset, and if you write things down. There's a reason we have contract law, after all. I've run some fairly successful businesses with people I consider close friends (but we were generally business partners before we were friends.)
Eventually one of those businesses hit the wall, and there was a bit of squabbling over money, but I still consider my partners in that enterprise close friends. It helped that we had contracts spelling things out. I suppose it also helped that we were all entrepreneurs who had had businesses fail before, and we all knew that maintaining relationships with both partners and clients, and not looking like greedy jackasses to either, was a lot more important to our future prospects than winning a fight over the money we had left would have been.
It also helped that we had become very close by then- I would consider some of my partners in those businesses as close as family. That's a double-edged sword of course. There's nothing more bitter than a family dispute, and a "family" dispute between people who lack actual blood ties can get ugly indeed. But we were very close, and the fact that they let me take most of the money with me smoothed things over to a remarkable degree . We remain close.
That said, I think this might be a difficult time to start a juice business. If you're wicked brave, wicked intrepid, and wicked willing to fight the system, be my guest. I wish you luck. But there are easier ways to make money, ways that don't involve fighting federal agencies. That's the sort of thing I hate to see in a business plan- "1) fight the feds" is a precipitous first point.
