How Much Should one expect to pay for a pair of good doors for a Mk.3 Hornet ?

A colleague of mine (Vincent) is planning to restore his Mk.3 Hornet which though in good mechanical order, is showing all the signs of
having been left out in all weathers for the past 2 years. This car was imported into Ireland from Scotland and will require attention to the
sills, floor and boot floor/rear seat area. These defects will be tackled in due course with new metal but both doors are beyond repair.
Hence my question.
