Go for LLC. LLC is good for small and startup organization. It is costly at beginning but worth it. You need to publish in newspaper, depending upon newspaper your cost varies. LLC doesn't have personal liability and tax is less. There is a tax bracket for income.
However S crop has a higher liability and you'll be taxed high. If anyone sue you, you may need to pay from your personal assets too. S Corp doesn't cost much to register. It may cost around $200(depending on state) But if you go by lawyer, then i can't say the price
