It helps to already have a potential client or two, before even starting the company (or a financial cushion for one, two years or the ability to survive without financial support, i.e. parents, partners, farming community, etc.). Since you want solid and concise information, your country would also play a big role, but I'm guessing omission of that information is an indication, that you're probably in the US? Every country has their own legal quagmire when it comes to concise information about founding a company. If you're in the EU, thanks to their open borders policies, you even have the choice of choosing a country and the corresponding legal framework. Nonetheless, (me from Germany) I think this is valid in the US too, are you sure and have put some thought into whether you really want to create a one-man-show company and not be a freelancer? The latter choice is often easier, especially from a bureaucratic point-of-view.
