I do not know any that breed on a big scale but the owners from Pinellas county reptiles have two iggy's breeding and they will have babies in the up coming season.
Last clutch they had went fast and the babies were amazingly hand-able. They are green iguana's but the babies almost looked blue. So you could look forward to a nice green iguana in the future.
Located in largo fl. They do ship.

Just a thought. :]
