You definitely need insurance regardless, but an LLC is completely unnecessary. It’s just a bunch of extra expensive paperwork and tax filing that will not protect you in court from liability. The liability of the business would just be passed on to you. The reason being is that an attorney can easily prove that the business is not truly separate from you as the owner/operator.

If you are planning to hire employees immediately, it might be a good plan. But if not, I wouldn’t bother.
