It is true that some states allow you to withhold an address on a label if you are listed in a phone book. While I understand that it may be annoying for customers to show up uninvited, it’s worth noting that I haven’t heard of this becoming an safety issue for anyone. The “by appt only” sign is a good idea.

Here’s a blog post I wrote about pricing: http://forrager.com/2016/05/the-price-is-wrong/

Since New Jersey doesn’t have a cottage food law, you’d need to use a commercial kitchen. http://forrager.com/faq/#commercial

I do not think that any cottage food law is sophisticated enough to specify bartering transactions as monetary transactions that count against your sales limit. If it were me, I’d only count monetary transactions against the sales limit, and I’d be highly surprised if ignoring bartering transactions were illegal.
