No person who breeds chameleons, and let alone has no chameleons at the current moment, should even be thinking about making a profit from breeding chameleons... Which it is obvious that you are wishing to. Most breeders aren't making yearly net profit, even after their forth or fith year, then they have to slowely make back the money that was spent during the first years.
Selling chameleons should not be a goal. Successfully keeping your first two chameleons in top health from the juvinile stage that you buy them at, until they are the age when breeding is safe, should be your goal. Making profit, let alone breeding, should not be on your mind, as you need to concentrate on keeping chameleons alive. Stray from your goal once... and the tragic effects are often irreversible.
