How to Succeed in Business...

Michael and I are working on officially starting his flooring business. After searching the internet for many days, I am surprised to find that there isn't one place you can go to find out what you need to do to start a business or tips about starting. I mean, there is a site for the county business license. There are sites for starting your LLC. There are sites to assist in designing a logo. Etc, etc, etc. But what are we missing? How do we know how much insurance is needed and how to get it? What else needs to be done? In what order does everything have to happen? Do you have to have an LLC in order to open a bank account in the company name?
Does anyone have advice? Is there a site that I am missing? Is there a book I haven't found?
