First off you are in way too much of a hurry to breed a species you know very little about and second Zonosaurus quadrilineatus is a very difficult species to breed let alone hatch eggs! There are no book or manuals on how to do this period. Very few of us dedicated breeders have done this let alone on a regular basis.
If you scroll down this forum you will find I have left Basic information on husbandry, acclimation, breeding, incubation of Z.q and other species of Zonosaurus and Gerrhosaurus families.
Take the time to learn about the Plated Lizards you have now. Are they parasite free? Is their housing set up appropriate size? Is your substrate deep enough and does it allow for burrowing tunnels? Is the correct nest/hummidity box set up properly? Just because they are a few years old does not mean they are in breeding condition. Do you know how to sex them and when to sex them? How long have they been acclimated in your home/their appropriate cage to allow them to consider breeding themselves?
One cannot just purchase lizards, put them together and expect reproduction. You have responsibilities to them before you can consider breeding. Go scroll back down the "Plated Lizard Forum" pages to read the previous postings by myself and others. Plan on at minimum 8 square feet of cage floor with a least 3" deep subsrate, two spot lights, Ceramic tiles, cork bark tubes, terra cotta saucers, and other previously listed materials. Check you ambient room temps, cage temp/cage spot light temp/ tile temp under spot light, diet, and alot of other questions to answer.
When you get the basics in order and let them acclimate for a minimum of 3 year stable enviornment then they might consider breeding.
Start reading and providing better care for them first. Then I may help you get started. If all you want to do is feedem n breedem then don't waste your time or thier lives. This is no easy speices to breed!! I understand your excitement but slow down and look at the real picture...responsiblity & dedication to the animals. It will not be cheap either.
I have a male zonosaurs for over 3 years already, and recently brought him a female 2 days ago. They are currently living in different setups, and i intend to introduce them in a week or so. **Anybody wants me to modify this blind date, feel free to do so**
