I'm not a security expert.
Requests for comments from career security experts: is this any good?
NIST generally publishes excellent guidelines on operational security for academics, and commercial firms.
As a "solo" anything you are going to fail sooner or later. At minimum one requires a gray-beard IT person/consultant with a vested interest in your survival, legal consultant in corporate contract/employment laws, legal consultant in Intellectual Property (Copyright/Trademarks/Patents), a commercial Accountant familiar with tax laws, and a customs broker to handle international shipping rules.
No one is an "expert" all the time, but without key people a small firm will get squashed pretty quickly. =3
Yes, this is pretty good and you should most definitely read it - https://news.ycombinator.com/item?id=50347164
