What you could so is become an LLC which means that you can't get sued if something happens. It's like insurance. I think it's just a one-time payment of $700, and then you can use that LLC privilege for anything you want. So if you wanted to switch to a different product alltogether, you could.
With a LLC (
LIMITED loss co.) are you responsible up to a set amount, or totally unresponsible?
I would see if there was a small business group in my area and pick some brains. That would be a good way to start out......
