As a retired lawyer my advice was often to not bother with an LLC or corporation. They are only valuable to limit one's liability in the event of a problem, and most people just continue to operate the same way they did before incorporating. If they do this it is a simple matter to "pierce the corporate veil" if there is a problem and avoid the limited liability. The idea is if you do not behave like a corporation others do not have to recognize it either.
If you really want to limit your liability either research how to properly conduct your business within the corporate pattern (annual meetings, board of directors, annual reports, etc.) or, in most cases, just purchase sufficient insurance. The insurance may cost less than the annual fees- state, accounting and legal.
