I would go with a 28 quart tub: http://www.homedepot.com/buy/storage...l#.UGtum7Q2KRk
With a Zoo-Med UTH (medium size, regulated by a good thermostat) : http://www.petsmart.com/product/inde...ductId=2752652
To make holes I would get a cheap soldering iron, and melt the holes in.
Make sure that the room that the tub is in stays above 75 degrees.
