computer repairs/ builds or auto. If you love Mazdas and have the ability to enhance the technology in our cars, you could build a heck of a business.Sort of a Jack of all trades. I'm a single dad by day, I bar-tend evenings and weekends, and I do side gigs for computer repair/custom builds or auto. Really hoping to start my own business doing more of the latter as that's where my passion lies. Anything techie or electronic peaks my interest and I love to get hands on and build or repair hardware.
