If you want a nice animal plastic enclosure that will cost you around 400 or so bucks. Substrate and mice do have a cost over time and he said he didn't have cash to throw around. I was just making sure he is aware of the costs. Plus add in a good thermostat and you have another 200 dollars. Add shipping and also hides, water bowl, temp-gun, humidity/temperature gauge and you will reach around 700.
