I like commercial, but decided to do just residential service work for now. My license is for residential, so I stick with it. I am avoiding new home construction, as it is demanding and too competitive, and I don't have the business experience or connections to compete with the big names.
Most electrical contractors here are too busy building homes to have time to mess with small jobs. This is my niche, and as a subcontractor, I always get paid from the company sending me to the homes. I won't get rich, but if I make enough to live on, and keep the customers satisfied, I am happy with my choice.
