$5,000 a month? Honestly, it just depends on where she lives. If she lives in California, then probably upwards of 80,000 a year. If she moves to a cheaper state and doesnt have to live in the expensive city she can probably do fine with 50-60k a year since its technically a part-time job (although preparing things for stream, marketing, working on assets, video editing and thumbnail/schedule making probably takes longer than the actual streams).
