On the subject of how fast they grow? Here's a pic to illustrate the difference in growth rates depending on feeding and temps! These two are clutch mates!
As far as pricing and size etc, I deal primarily with coastals (Morelia spilota mcdowelli) and they are prolly the biggest spilota you can get in the states. My males stay around 1000-1200 grams and 4/5 ft long (primarily due to how I feed them) females can and will get big 8ft or so, and 4-5kilos (1-2lbs, I also keep bps and have gotten used to the metric system). Pricing for just regular run of mill carpets 75-150 is about right, really nice jungles will be about 3x that amount. Yrlings and adults depends!
On breeding. They are about the simplest pythons to breed, you can, and I have, bred them on accident! Males are mature at about 18-24 months, females can be bred at 2.5 yrs but usually take that extra yr and go at 3.5!
Second getting the book, and highly recommend carpets in general!!
