I found Legal Zoom very helpful for advice and assistance in opening my business. The website also keeps members updated on all procedures necessary to keep a company in good standing. Legal Zoom attorneys are available for advice on an ongoing basis, which is ideal for new business owners! The site also connects members with a comprehensive financial and accounting service. Very helpful and supportive. Excellent! 

Rocketlawyer is the cheapest way to quickly incorporate. I needed a tin (tax id number) for my business to get a business checking account. It was quick and easy to go through rocketlawyer. The automated web forms made it simple.
