Is there a website that makes large rabbit hutches, or makes custom ones?

I feel in love with this bunny at a pet store. I already have two bunnies, but I really want one more. The problem is that it is an adult lop eared bunny, and it's way, WAY too big to fit in a normal cage. A good sized hutch would be five feet or more. I was also thinking of maybe just getting a large exercise pen, or a five foot rabbit run and using that as it cage. I'm not sure what to do. Can you help me?
