i guess when you're thinking of starting up a business, you need to give it some time till it starts paying off - basically, you can't expect to start living off your website straight away.
one important thing is, to make a good start-up, you might need a press release. Then it's basically you who would need to create some ads, put them on content submission sites, and make sure they're interesting enough for people to be actually wanting to see them/link to them.
i see the rise of a website as a process with many variables. The most important thing would be to have as many people talking about it [as in linking to it] as possible, your google page rank would raise at that point, which would automatically make people visit the site.
personally, i would put my hopes in a couple of ways:
- make a press release, so that bloggers start writing about it, and those bloggers need to be from the community you would think of as your primary target
- make an outstanding viral video that would promote your site.
