Karen - Glass companies which are usually local...try your yellow pages. These companies on occasion sell used wall mirrors at a reduced price and would also install. Also, they are able to put together medium sized pieces if they don't have single continuous piece that would cover the entire wall. Putting together medium sized pieces requires strips of mirror along the adjoining seams which might be annoying due to its mosaic effect (multiple reflections) on the image. Try to reduce it by using thin strips of mirror just enough to cover the seams.
