This seems a niche market where clients (museum curators?) find you via word-of-mouth and trade exhibits rather than “a quick google search”? Then consider something unexpected, something that describes your passion and take on the job rather than the job itself. Exhibiting Prehistory is punchy, but to me it sounds like a caterer called “Serving Food”.

E.g., The Brain Scoop (Emily Graslie’s show from the Field Museum) is memorable and reflective of her approach, but not obvious.
