Now the S-corp and LLC are good routes to go with for protection but, with a S-corp can be difficult to form because I taken a accounting class recently and with s-corp are more regulated with striker laws by the IRS. which personal my final verdict goes to LLC because you are a single person in this business if I'm not mistaken which will get the job done with this option.
