There are many rack manufacturers out there if you are looking into PVC racks I would recommend C-serpents and Animal Plastics, Boamaster however not so much check the BOI for reviews.

If the room temp is low you will want an enclosed rack.

If you buy animals that are breeding size I would give them 6 months to acclimate and make sure they eat for you before even attempting to breed, adult females are tricky and take a while to adjust.

For 2 clutches build your own incubator out of a cooler and remember the single most important piece of equipment for your incubator will be a RELIABLE T-Stat.
