She could likely make more money doing periodic consulting gigs versus a regular part-time job.
Did she use the facilitation skills at any previous employers? If so, perhaps she could contact those previous employers and let them know she's available for $xxx per day. Training and facilitation gigs aren't impossible to find. Demand for graphic facilitators does not seem to be as high, I believe primarily because it simply isn't as well-known.
She could also join her city's professional organization for facilitators, such as Association for Talent Development (
https://www.td.org/), attend some local meetings, network, and get her name out there as a starting point.
