Money makes the world go around?

So how to start a serious website?

The idea is here, now it is time to find out, how much it costs to build and operate - and where to get the profit from.

Next task is so sneek around the net, what resources needed for similar ideas, what resources needed, where can we fail, as many developers do.

Use managed hosting? I will get a PC, can't believe that only for me, and needs loads of money to run it. Around 150 USD/month before starting. And we need system software, database, etc on each. :(

And how many servers we need? Who knows? An usual trap for a web2 company is to grow faster than the income flows in. The existing servers are not enough, and timeouts show up. if the fanbase is big enough, they can survive, othervise a site can loose its visitors in no time. Or, the worst case is to hunt venture capital.
But hunting capital is not the best idea. They usually more eager on securing their investment, than risking and building something great.

I like people, even rich ones. But if possible, get their wealth elsewhere.
