Startup cost: $500 - $5k

The low-end estimate covers basic tools like a hammer, chisel, and safety gear, along with minimal advertising on social media. The high-end estimate includes professional-grade tools, a small inventory of stone, a website, professional branding, and more extensive advertising. Essential costs include tools and safety equipment, while optional costs involve advanced tools, a website, and professional marketing. Hidden costs might include maintenance of tools and unexpected material costs. Online communities often suggest that while starting costs can be low, expenses can increase as the business grows.
