@TBTINT18 It's a good idea to consult with an attorney for legal entity advice. For tax advice regarding entity decisions, it is different for each person and may also depend on state rules. In many cases, an LLC is a common option as there is flexibility with how you are taxed.
Regarding paying that estimated taxes, you have to do that quarterly whether you are a sole proprietor or a disregarded LLC for tax purposes. If you choose to register the LLC entity as an S-Corp or C-Corp, your withholding taxes will take care of the quarterly reporting for you.
