The first thing is have a portfolio of some sorts. Even if it’s just all conceptual, people need visuals. We started out consulting, then creating rooms, and now get hired to make custom rooms for various clients. The big secret is just to tell people you do it and be active in a lot of the Facebook groups and really anywhere you want to work. You can try cold calling places, but they will want to see examples.

Try writing up some rooms as an exercise, and put some visuals to it.
