You're still not making sense. There's no such entity as an S-corp. An S corp is a tax election (as he told you). If it is an LLC, it's an LLC regardless of how it is taxed.
It doesn't matter if you own the property by a corporation, an LLC, a partnership, or individuals, it has to be witnessed by a notary (or one of the other listed court officers). I don't know where you got it into your head that corporations (if you even had one) were somehow exempt from this requirement.
If it is the case that you personally don't want to go stand in front of the notary, then you can give power of attorney for someone to sign for you. Frankly, as confused as you seem to be, I would suggest the attorney in fact, be in fact, an attorney.
