Hello, I am a single person doing some SEO, and reputation management work in Washington State. I have a Sole Proprietorship for my affiliate marketing stuff, and have been using this business license to conduct my other business out of convenience. My question is: Should I consider forming an LLC? I'm a bit of a worry wart. While my current prices never exceed more than $299/month, I'm still worried if a client isn't completely satisfied with my work that they may sue me for everything I got. People are vicious. While I've never had any threats (~5 active clients atm), I still want to cover my tracks should someone want money from me for whatever reason. If I form an LLC, what state should I file it out of? Washington state is pretty corrupt and the taxes here are ridiculous. Thanks!
