Does anyone have good advice about the legal side of starting my own business?

Check with the nearest Small Business Administration office and SCORE (Senior Core of Retired Executives)

That venture is not an easy one. Be care what you do and when you do it. If you have the option to avail yourself of JAG, do it. IF not, tread reasonably with the SBA and check out any military friendly legal aid societies in your area for advice and council. Being a self-proprietor is tricky tax wise and the amount of paper you have to keep up with and fill out in mountainous. Good luck and message me if I can be of any further specific help.

Whatever you do have it blessed by an attorney before you start up the business.
