Great post! Lots of good information there!
I would also like to add in a few things. First, you must also consider how difficult it will be to sell your babies at first, before you have established a well known reputation. This is especially troublesome for someone like myself, who only has a few clutches a year. I would classify mine more as a self sustaining hobby than a business, and I still have a few thousand dollars and countless hours invested in animals and supplies and care. There is a certainly a lot to think about!
