Stable income: Somewhat stable

Offering transcription services can provide a moderately stable income source for those who dedicate time and effort. From my own experience and online research, many people earn consistently but may face fluctuations due to market demand. It's not as predictable as a steady job but can offer a decent baseline income. Setting up costs range from minimal to moderate, mainly requiring a computer and transcription software. If your best friend quit their job for this full-time, I would say they have a fair chance of success with some dedication and resilience.
