Startup cost: $500 - $3k

Setup costs range from $500 to $3,000 depending on the approach you take. At the minimum end, you might only need a basic toolkit for equipment diagnostics and maintenance software subscriptions. On the higher end, investing in specialized predictive maintenance sensors, data analytics tools, and training programs can enhance the efficiency and accuracy of your services. Essential expenses include purchasing maintenance tools and software, while optional expenses may include advanced predictive maintenance equipment or professional certification courses. Hidden fees could stem from ongoing software subscriptions or sensor maintenance costs. Online feedback suggests that while starting costs can be kept low initially, they may increase as you commit to more advanced equipment and training. If a friend was serious about pursuing this side hustle, I would recommend budgeting between $500 and $3,000 for a solid start.
