An offbeat suggestion is to ask various target museums in your city if they
use temporary employment agencies, and then sign on with those agencies
indicating your specialized qualifications for museum work. A friend of
mine did this and ended up working for her "ideal" museum, the Metropolitan
in NYC.
Email me privately--I have a curatorial assistant position open that might
interest you if you are willing to relocate to Indianapolis.
