Restoration of ladies writing desk

I am restoring an old writing desk and have a bit of a problem. The four legs are turned quite elaborately and are "broken" at the half height by a shelf, so I need 8 identical legs each 280mm long and about 50 mm round at the largest size. Can ayone point me in the direction of someone who can produce such items at a reasonable cost?. Seven of the eight have borer activity, which I can treat if I cannot get 8 new ones, but one is borer and water damaged beyong rescue.

Thanks
Ingin
