Landmark-approved Windows and ironwork

B’stoners, I need your recommendations for new windows and ironwork. Landmarks Preservation finally tagged me for non-compliant Windows and ironwork on my front facade (don’t hate, it was there when I bought). I know there are lots of great neighborhood iron workers and window guys, but I need the full work up: architectural drawings, LPC filings, and install. What experience can you share? TIA!
