basement finishing

I have 12 years of personal handyman experience from electrical to plumbing and drywall. I was working around houses, building my own basement, doing everything possible from wiring to framing. I have also attended some business classes in college. I have my hard-earned savings to invest in the business.
I think it's better to mainly focus on framing, interior, and drywall. While working all these years, I even have the tools that I could use.
So, I think I have all the basics in place but I would like to ask
whether I need to register the business with a Sole proprietorship or as Incorporation?
I don't know about the legal procedures and any advice on this would be helpful to me.

Thanks
