I am a stay at home mom that has been doing house/pet sitting (done this for friends, now getting recommend for others and not sure about liability with that) as well as tutoring and writing online/blogging as side jobs for a while and not make much money at it. I am starting to make more at all three jobs. I do not have a business or any licenses to date. I am wondering if I can start an LLC or sole proprietorship in which all three jobs are in one company or should they be separated into three businesses? Should I put it under my name or establish a separate business name for liability?
