Are there any cages for crested geckos that would fit a stand that has these dimensions?

We have a stand that is about 33 inches in length and 14 inches in width. Our two cresties are starting to get larger and we need a cage that they could fit into more comfortably at their full size that fits the stand. It also needs to have something that we can fit a humidifier for geckos up to it. Is there any where that we can buy a cage like this.
