How Would You Start A Business?

Cosine Jeremiah asks: "I'm interested in starting my own business, but I'm not sure where to start concerning legal and tax issues. Sure, I suppose I could go ask a lawyer, but I want to know what to expect before I have to put down any money. And I'm not sure I can trust just any lawyer I accidently end up with to give me the whole truth, such as what all of my options are and all of the pros and cons of each. Should I create a corporation? What kind of corporations are good options? Or should I make the business an at-risk venture? And which special tax forms do I need for each? Right now I don't really know the difference. Surely there are many people out there that have gone through this and can share their experiences, and just as surely there are many more people than me wondering about this stuff?"
