I have been building a bootstrapped SaaS business for the better part of a year working late into the night most nights per week. I have never spent anything aside from my own time and a few negligible expenses to get this system where it is now. Now that I am gearing up to launch my SaaS to the public, I need to start hiring out certain things like logo design, mobile add-ons, etc., as well as prepare to accept recurring payment for monthly services.
As I live in California, what steps must I take to "do it the right way" from a business/legal/financial perspective if I plan on continuing to be the only person working on this project?
