Startup cost: $500 - $5k

The low-end estimate covers basic tools like a multimeter, screwdrivers, pliers, wire strippers, and safety gear. It assumes using personal transportation and minimal advertising through word-of-mouth or free online platforms. The high-end estimate includes advanced tools like power drills, conduit benders, and a thermal camera, as well as professional branding, a website, insurance, and paid advertising. Hidden costs can include licensing fees, ongoing tool maintenance, and unexpected equipment replacements. Online communities often highlight that while starting costs can be low, expenses can increase as the business grows.
