Where to buy a glass front wall hanging shadow box for wedding goblets?

We were given some nice engraved goblets and cake servers as wedding gifts last year. I would like to put them in a glass front shadow box but can’t find one to fit anywhere! I’ve tried the usual stores like Michael’s, JoAnnes, Target, etc. I even tried searching online. The box would need to be 13 inches tall by about 15 inches wide and 2 3/4 or 3 inches deep. I would like it to have a glass front. I saw a few that were over $100 bucks…but I’m sure we can do better than that!
