Texas Contracting

Merry Christmas
Considering starting an Electrical Contracting business in TX, I do carry a TX Masters License. I am in the early stages so I have many questions. I know TX requires all people working on a project to be licensed, including all apprentices. I also know that trucks need to have Contractors name and license number signage on them. Where would be the best source to find any other details of what Texas requires. Anyone have any PDFs or Books that they wouldn't mind sharing?
