Confections

I make candy. Mostly chocolate. I want to start selling it. I’m going to start with taking custom orders and selling at private events (events with a lot of people but not open to the general public). What do I need for this? I’ve been told that I’d be fine with just bringing them, pre-made and pre-packaged but suddenly I’m being told that I’d need a industrial grade kitchen, food certifications, and even a business license (partly just because I was thinking of giving it a name). I do have a food sanitation certification. I studied this in college and with an internship a few years ago and I don’t remember any of these being needed for something simple as candy being sold privately. So which is right? I’m so confused and am getting very discouraged.

As I started, currently, it’s just general chocolate. I make stuff for my co-workers and a few friends (free of charge) quite often. I’ve also done chocolate covered cookies (Oreos) and pretzels and would like to expand into chocolate covered fruits and graham crackers as well, if that makes any difference.
