First of all, the website looks dead. When a visitor comes to your website and sees that no one else made any posts, they will not post anything also.
If I would have visited your site and it looked really busy, I might have been tempted to also post something. Once this happens, you can do affiliate marketing or pay-per-click marketing.
So, first fill it up with information so I looks like a lot of people are using the site. Then, once a visitors ends up on your site there will at least be a chance for that visitor to post what they Want/Need. The way it is right now (empty) there is basically no chance.
Very good idea for a website, I see a lot of different ways to make a profit from something like that but your domain name is just horrible. You will have to actually market the domain name as well just so that people could recognize it as a brand. For example, when I see the word "buezit" I don't think right away, "Oh, I can post something there so that I can find the cheapest price for an item very fast without any effort". When I see the word "Geico" I think cheap insurance (even though the name does not have anything to do with insurance and they are not cheap). This is because there was plenty of brand advertising, propaganda-style media.
Since I gave you some much of my time to reply to your question, you are obligated to look at my post
