I think you need a reality check.
From what I've heard...a venomoid procedure usually costs about $400.
This is on top of the purchase price for the animal.
If you cannot afford the market price for an animal, how can you afford to house them properly?
You also provide no information as to your age or experience which is very important when dealing with venomous reptiles.
As far as venomoids go...my feelings are "get a non-venomous snake".
This is a topic that has been beat to death on most herp forums.
