The Idea:
Earn money tuning other people's pianos.
How it Works:
This skill is an easy one to learn for people who are musically inclined. You'll have to invest in the tools for tuning, but once you do you can sell your services to home owners of valuable pianos as well as to businesses or churches that have a piano that needs tuning. You can supplement your tuning business by becoming a certified piano technician able to service and repair pianos.
How Much Can You Make:
A basic piano tuning usually runs around $100 for approximately one hour of work. You can charge more for major repair jobs such as restringing or regulation.
