​Playbook to start a small business from 0 to 1

I’m curious why there isn’t a platform that aggregates some experts from various industries, where they write and sell playbook on how to start a small business. I feel a lot of the traditional business are very mature. The process from 0 to 1 is very standardized. I hope there could be a playbook, just listing out 1,2,3,4… with links to just one of very limited options to get the necessary things done, so that I can just follow and quickly stand up my business. This will significantly lower the barrier to enter a different industry. Currently I have to research, collect resource online on the things that have been done by other people millions of times.
