Startup cost: $200 - $2k

Low-end estimate: This budget covers basic tools like screwdrivers, tweezers, and a heat gun ($50), a small inventory of common replacement screens ($100), and basic online advertising or local flyers ($50). This setup is for someone who wants to start small, possibly working from home, and focusing on a few popular phone models. High-end estimate: This includes professional-grade tools such as a high-quality heat station, precision toolkits, and a microscope ($500), a larger inventory of screens and parts for a wider range of devices ($1,000), a professional website and online advertising ($300), and possibly a small workspace rental ($200). This setup is for someone aiming to establish a more professional and scalable operation. Essential at launch: Basic tools and a small inventory are essential. Optional items include advanced tools and a professional workspace. Hidden fees: Shipping costs for parts, potential licensing or certification fees, and ongoing advertising costs. Online sentiment: Many say it's low-cost initially, but expenses can increase as the business grows or if aiming for higher quality service. Advice to a friend: Start with the low-end budget to test the waters, but be prepared to invest more if you want to expand or improve service quality.
