HAGAJI PLEASE READ=> I have knowledge of what you are looking for. My sister, Sandi Myers who is married to Ken Hagmueller, breeds and raises dachshunds in Waxahachie, Texas.
They also make specialty crates that are sold all over the world. Maybe you know her, or maybe you don't, but I would love the opportunity to work for you on this project because I know exactly what to look for on the internet! I put 20 hours but I think I can do this in fewer hours.
