Stable income: Somewhat stable

I’d rate it a 3 out of 5 because while there is a decent baseline demand for tattoo removal services, the income can be unreliable at times due to factors like market saturation, competition, and fluctuating client interest. It's not as unpredictable as a 2, where income swings wildly, but it lacks the consistent predictability of a 4, where most months are similar in earnings.
