Attorneys. No matter what, make sure you have an attorney on retainer. People sue and get sued, and businesses have much more exposure to a lot more and varied types of people. If you're an even moderate business success, you'll be getting calls from lawyers or you'll be getting someone who tries to skirt your policy based on a loophole in your TOS/AUP/etc. Lawyer up. If you don't have the money for a lawyer to review your business with you, you're putting yourself and your customers at a risk that many would deem unacceptable.
