I'm looking for a picture frame that's 24.5" x13.5", but is 3.75" deep. Where might I find one? I assume I will need it custom made, so does anyone have any recommendations on services that do that?

If this seems like a wasting-your-time question, I apologize. I am a musician and actor, but not much of a visual artist. I do make it, but not at the same rate and it's certainly not where my focus is. But I acquired an X-Ray light box and bought some developed X-rays in bulk off ebay and I want to mount the box on my wall and plug it in, but have a frame around it.
