Opinions Wanted

Hi folks. I have recently started a part time wood working business, and
have been asked to make a couple of display cabinets to hold a doll each.
These cases measure 16" X 16" square and 32" tall. Glass on all four sides.
Made from solid birch, and were left unfinished for the buyer to finish in
whichever manner she wanted. I charged her $120.00 canadian for each case.

I was wondering if there would be a real interest from doll collectors for
these cases. They could be custom made to size of course, but I am gauging
interest in the area before i bother spending more time on it.

Thank you for your time.
