Startup cost: $500 - $5k

Low-end estimate: This budget covers purchasing a few used iPhones from platforms like eBay or Facebook Marketplace, basic cleaning supplies, and listing fees on platforms like eBay. It assumes minimal marketing and no additional tools or services. High-end estimate: This includes purchasing a larger inventory of iPhones, professional cleaning and repair tools, a subscription to a phone-checking service like CheckMEND, advertising on platforms like Facebook or Google, and possibly a website setup. It also accounts for unexpected costs like shipping, returns, or repairs. This budget allows for a more professional setup and marketing strategy.
