Metal Bay Window repair??

[Mike B.]

I'm purchasing a philly row home that has an original metal bay window on the 2nd floor (similar to pictures below).  It's in ROUGH shape.. unsure if it can be saved, but I would like to attempt to save it and/or have it restored to it's original glory. 

Does anyone have a contractor to recommend that specifically does this restoration work? I have newer windows in there already. Just need the metal fixed up (read: large holes on bottom, etc) and painted to preserve it. Trying to forego doing new vinyl siding which would be $1500 (approximately).  Plus an original bay window looks awesome. 

pix below are of my past rehab where I was lucky and the original bay window just needed to be pressure washed and painted.  

Thanks in advance for recs.
