Keep in mind there is 26 ways a corporation veil can be pierced. You can set up LLCS that report as S Corps (That's what I do) or just an S-Corp or LLC online yourself, an accountant or lawyer can do it. If you're not making money yet I would go with an LLC. You can use The Company Corporation who are suppose to be really good and will give you 50K in legal service if your corporation is pierced. Anyone can sue you for anything no matter what you do! An LLC protects your personal assets but that doesn't stop someone from going after just have a better chance of the judge dismissing it.
Again this isnít legal advice this is just how I roll.
