Are LLC, business name, website, and cell important at the start?

[Jordan James]

Hey everyone. I'm a brand spanking new investor, but I have no idea of where to start. Like many people, I have little (read - almost no) funds, so I have to figure out where to spend money at the beginning. I've read in quite a few places that it's important to have things like an LLC, website, a phone number devoted to your real estate ventures, and business cards to bridge the credibility gap. However, I'm wondering - what are the absolute most important items you have to have to start your business?
