Request: Looking for an indoor led backlit sign

Moving my law office and want a relatively simple, led backlit sign for inside wall. I am thinking of painting the wall the dark blue, and then painting the mountain lines in the background, so I would just need the illuminated signage.

Can these be run off batteries or do I need to have an outlet available?
