Perform guitar setups and repairs (action adjustment, fret leveling, nut work, full refrets) for gigging musicians and music teachers, who need this service 2-4 times a year as instruments respond to seasonal temperature and humidity changes and typically stick with one trusted repairperson once they find one.
A basic setup kit (action gauge, straight edge, radius gauges) runs about $133, though the presenter notes it's usually missing truss rod wrenches; a genuinely complete kit with nut files, fret rocker, feeler gauges, and wrenches runs $250-400. Local shop rates: basic electric setup $60-120, acoustic $70-140, fret level and dress $150-300, nut work $60-120, full refret $300-600. Per-job material cost is typically just a set of strings and a small part.
Someone with (or willing to develop) genuine guitar-tech skill, who understands that trust and repeat business come from doing quality work on a musician's primary instrument, not from marketing.
The recurring-need mechanic (2-4 times per year, driven by seasonal humidity changes) and the low per-job cost make this a genuinely attractive margin business, but it requires real technical skill that takes time to develop — this isn't a business you can start competently with just the tool list alone.
