Temporary Cage Options

Hello, I was wondering if anyone here had any good ideas for a temporary cage on the cheaper side that can fit two adult chinchillas. I'm going on vacation in April and I'll be gone for about a week. I have a second cage but it's very old and it is now unsafe to use. Money is kind of tight so I'd rather not buy a MidWest. Something that's easy to set up/take apart for boarding purposes would be wonderful.

Thank you in advance.
