There are only two places that I can think of that will ship a fully assembled plastic cage with heating already instlalled and that is Boaphile Plastics, and Repti-Racks:

Some other places that ship fully assembled cages, but you must add the heating elements, depending on what type of reptile you intend to keep:

Some of the other cage manufactures ship the cages disassembled to make shipping cheaper, but they will install Flexwatt, Under Tank Heaters, or Radiant Heat Panels to the appropriate cage panels if you request it:
