Framing a 77.5” x 46” world map

I got this laminated world map I’d like to hang on the wall in my office. I’m having a real hard time finding a place to buy frames that go this large online. Does anyone know of a place before I have to resort to DIY’ing it? Much appreciated

Here’s the map if anyone’s curious:
