My 36 year old son took a sewing machine repair course after he lost his other job. What began as a part time fill in job has now become full time. He charges a reasonable rate to encourage customers to have their machines serviced more often. A win-win for each. He loves what he does and can not understand why more people don't become involved with this profession. He services all makes and brands. And lives next door to me. Now all I need is one of my sons to become a doctor or dentist and life will be perfect :-)
