Be extremely cautious while communicating with the owner. Even if you casually agree to buy the domain via email, the communication might be used against you in court as a legally-binding contract should you change your mind. Until you’re absolutely certain that you want to make a deal, agree to buy the domain provided that all the terms are agreeable. This will leave you an escape hatch if things go south.
A Virtual Private Server (VPS) is an independent, virtual partition on a physical server. Think of a server with different "containers" within it. When you sign up for HostPapa VPS hosting, you get one of these containers to manage as you wish—install applications or scripts, and arrange your web files the way you want. It's private, secure, and flexible.
Why? Because word of mouth only gets you so far in the internet era. People discover new businesses—even local business—via Bing, Google, and Yahoo. The days when they'd just look you up in the yellow pages are long gone. If you don't have a sharable website address, your chances of building online word of mouth via social networking plummet, too. In other words, no website, no discoverability, no money. Of course, web hosting isn't just for businesses. You may want to host a personal website or blog, too. Either way, the services here have you covered.
In housing terms, VPS hosting is like renting your own apartment in a larger building. You're much more isolated than in the roommate situation mentioned above; it's still possible that a neighboring apartment could causes annoyance for you, but far less likely. In web hosting terms, Site A's traffic surge won't have nearly as much impact on Site B or Site C. As you'd expect, VPS hosting costs more than shared hosting. You'll pay roughly $20 to $60 per month.
