I am looking for someone to build me a new style concertina. I don't need any single notes, I just want all one-button chords - even if they are only two note chords. I am looking for something simple to play that will accompany my voice - getting a bit too old to lug my guitars around :-} Is this something that can be done? If so, what will it cost?
