Welcome!
I also agree with what's been said so far. On top of Animal Plastics and Reptile Basics, some other PVC caging manufactures out there are Kages (currently a 9-12 week lead time), Focus Cubed Habitats (currently a 10-20 week lead time), and Custom Reptile Habitats (currently a ~4 week lead time for basic 4'x2'x2' models). I have a 4'x2'x2' Kage (with a ProProducts RHP) and it's a good enclosure.
