I'm still licensed as a sole proprietor. To incorporate I'm pretty sure you want to use professional services; accountant/lawyer. Seeing as how you're going down that road you'll need those guys for a lot of other crap-------once you're incorporated, especially with employees. Having a crew working for you requires pretty high level of effort and technical skills here in CA.
Generally speaking the accountants and lawyers will have all the correct software and expertise to perform those tasks efficiently. Your time and skill set is better utilized out in the field------selling, managing, installing and collecting. Just depends on how ambitious you are. I found being an employee fits my goals just fine and frankly, I guess i'm not all that ambitious.
