Very good advice above and you need to seriously ask yourself these questions before you attempt to breed.
A female boa should be about 3-4 years old before breeding and about as big around as a 20oz bottle of soda. Dumerils are a bit heavier-bodied than Colombian BCI, so a little heavier and thicker than that soda bottle should be expected and probably better for them. When you say your female will be ready in 8 months, how old will that make her?? Females bred too young often slug out or have very poor litters and stillborns.
To emphasize one point Satomi made is that Dumerils are notoriously very difficult to get started feeding. Are you prepared to assist feed a whole litter until they begin eating on their own?
Something else to consider. Dumerils tend to be hard to sell. Is your female high pink? Have an unusual or rosette pattern? What about the male? Unless they are exceptionally beautiful animals themselves, they won't likely produce better than themselves and the babies will be that much harder to sell. Any animal that is worthy of being part of a breeding program should be an outstanding example of the species. Some pictures of your girl would help and also any pics of the prospective male too.
