I think it's pretty safe to say you won't see "profit" in breeding corns unless you put the money in to get something amazing to start with. Candycanes are just specially bred amels. (usually amel miami, then selectively bred to achieve the cleanest white ground color.) And so are not really a good one to use if you really are in it for profit. Though I agree, they are very pretty corns! I have one
Bloodreds are still pricey, but nothing compared to Opal, and a few other multi-homo morphs.
I guess I just think if your goal is to profit, either spend the big bucks to start out with pricey morphs, or try a different snake. And if you have "normal" babies you are sometimes lucky to make 10$ on each. Not much profit there 
Corns are easy to breed and care for, so they make good starter snakes, and good business snakes if you have the time/space/money to produce all the "higher priced" morphs, because the lower priced, or most common morphs are everywhere and cheap. A great snake!! But you gotta breed BIG TIME to make money I think.
But get a pair and do it for fun
That's what I did, and it is fun
