This is going to sound crazy, but have you looked on walmart.com in the small pet section? They have all sorts of out door hutches that you order. They aren't made my walmart, they're made by another company. They have all kinds of designs with bigger runs and bigger hutch parts. I was looking at them the day before yesterday and they had some that were kind of nice. You'd just have to look.
I agree that the holes in the wire are a bit large. I would worry that the buns would get their heads stuff or be able to get out. OR something else would be able to get in. If you do get that one, you could get some chicken wire and cover the outside of the wire with the chicken wire or get 1" hardware cloth to cover the wire on the hutch.
I'll be honest, you guys could probably get the wood and stuff from lowes or home depot for cheaper than buying hutches, since you have to buy 2. You could go to the indoor lumber yard at either of those stores and ask them if they have the warped lumber packages. My dad spent $30 on a package and built me a really nice pretty large chicken coop.
The only thing is, the chicken wire or hardware cloth you decide to use can be pretty expensive. I think I would look into that, if I were going to have an outdoor rabbit hutch.
