Body resto costs

Hi,

I have a solid body from my 1969 Swinger 340 with all metal replacement performed.
This was done using all salvage solid materials refastened at factory points.

What I'm considering now is to see what it may cost to deliver all body components to a shop and have
all body and paint work performed.

I'm sure this is a wide range but what would be a sensible range for this car?
Just to give you an idea, I was quoted 6500 just to paint mine, base/clear and that's if I had all sanding and and prep work done.
