Sorry to make a second comment in a row, but honestly I think it would be a good idea for the OP to do thorough research to own a SPECIFIC species first- before making a thread asking about breeding and breeding businesses. Different species can have vastly different husbandry requirements and a lot of information to learn. Pick one you enjoy!
It would be most efficient if you take the time to at least research some basic husbandry practices about snakes first. Then you can also make a generally educated decisions, without everyone correcting you about basic snake husbandry that you should be researching on your own before even owning one snake.
Unfortunately the "complete terrarium packs" are never what you really need in snake care and frankly are overpriced, paying for equipment that you end up NOT needing, and missing important equipment that you DO need. There is no "terrarium pack", because different species have different needs.
Look into the ball python caresheet and husbandry section on this forum first if your goal is own a ball python. Or look into other caresheets if you choose a different species.
