CAD modelers doing work for the trade tend to try to categorize work
so that customers have an idea of cost before they send the job. More
routine work in the $125-$150 range, more complex work more like
$250-$300, unusually complex (or work for a difficult customer) is
quoted. That price does not include the resin, that’s usually another
$40-$60. That said, people charge whatever they can get, sometimes
more, sometimes less.
