1956 Ford Thunderbird Hard Top Convertible

Approximately how many hours and dollars are the average (normal) for a
complete repaint of my 56 Ford Thunderbird?  I have already paid the
restoration shop for 722 hours at $48.00 per hour ($32.5K) and the repaint is
still not complete!  I might add also that my car has been in the shop since
January 2019.  I personally bought all the paint and supplies and delivered
to shop during the month of June.  I realize that this project was a major
undertaking, but find it difficult to understand how this project could not be
completed within a six month period.  The car was totally dismattled for
painting (including engine, transmission, etc. and exterior lights and interior
seats) which will require reassembly at some point.  Including the labor
mentioned above, I have already paid out over $40K; and needless to say
I'm getting close to my breaking point.
