Is it as easy as opening a facebook page and selling babies?

Here are things I have already ticked off the typical list:
1. Incubator
2. Hatchling rack
3. Food for hatchlings
4. Breeding stock

Once breeding has taken place, eggs are in the "oven" or you have babies waiting is it just so simple as to begin selling?

Websites, for the majority, can be optional in my book. Many people are moving over to facebook and facebook groups to sell, so I'm no AS concerned about that though it would bean eventuality. I'm speaking more on...start up costs.
