We got our LLC.
The main reason was the legal protection it affords a business. If something were ever to happen only the assets of the business could be targeted and not us personally.
Also another benefit of the LLC is if we ever decided to open a line of credit or get a loan, everything would be based on the business and not our own personal credit and debt.
Your best bet is to find a good Accountant if you already don't have one and sit down with them and talk about your situation and future plans.
