My two cents:
Because you allready sell wild caught snakes, and are BROKERS, the presumption is going to be that the pair you have, because they are adults and you are brokers, are wild caught. This is going to be hard if not impossible to erase from most real buyers who are looking for a quality snake, not just some rehashed turned over import.
Emeralds have wide variety of behaviours as wild caught imports...some of which include regurgitation, refusal to feed out right, and overt aggressiveness. I would try and get the feed and shed records for these snakes from the original owner, who..if they truly are captive bred snakes, given the amount of money laid out, may have kept them.
The problem here is that the activity you are involved in:Brokering animals, lends doubt as to the authenticity of these snakes origins. Remember, if a person is looking to spend bucks on a snake, they want as much PROOF as possible that the snake is not only feeding, but has been kept by aas few people as possible in a given amount of time. If it was some cheap corn snake or perhaps Colombian boa or nicaraguan, then no one would really care, but with the kind of cash poutlay your talking about, it behovess you to do the best you can to SHOW the customer the LEVEL of care these snakes have received, even if you cant PROVE origin. If you cant show level of care and cant prove origin, you are going to have one hell of a hard time trying to sell them to people that are looking for good snakes. Your best bet is to try and sell them to another breeder, whose Expereince level allows them to deal with problems that may arise.
Just my two cents, more like 6 cents
