So I tested the market for a while last year at home. I was surprised by how many orders I got. It became difficult with a small child at home, but I have a better plan now. Last time I was also working another job that took my weekend delivery off the table. I want to go all in this time. The market is kinda saturated with at home bakers doing it non legite. I'm not going to worry about that since I assume they will fade away. What is your best advice on starting a legit at home service. Thanks.

What are the laws governing cottage-food business in your area?  They can vary tremendously from state to state and even county/city within a state!

Contact your local health department or whatever government agency oversees these type operations in your locale and see what you requirement are.  

Some allow in home businesses, some require a separate kitchen dedicated solely to your business and some require a separate facility all together.  

It can be fairly inexpensive to meet the requirements or it can be quite expensive...it just depends on what law(s) have jurisdiction where you live.
