Need an experienced plasterer

Can anyone recommend a good NYC plasterer who specializes in repairing/restoring prewar walls? Our neighbor's contractor put a huge hole through our wall, and the contractor/painter who tried to fix it did an awful job and it needs to be redone. The issue is that its old plaster walls with picture-frame molding, I'm told with a canvas underneath. Someone suggested replacing the canvas, while another suggested skim-coating but my worry is that will not match the rest of the wall. Would like an expert opinion before the wall is damaged further. TIA if you have any suggestions.
