I like the suggestion of breeding another species altogether. For ex, there don't seem to be many Angolan Python breeders around.
Anyway, research, research, research... first!
Don't discount books either. They STILL contain information I don't see turning up on line. If you want to breed BP's, I would start with NERD's book (Kevin - something?), the $80 one that just came out. You may decide to purchase animals just for breeding - as every one else has said, quality matters from a business perspective.
