I would buy some good backlinks PR 5+ then buy some banner space and do some seo on your own and make sure you have very unique stuff on your website you should have people running to your website.
Google is against buying traffic, especially when it is automated and generated by fraudulent means. Create good contents, get niche specific backlinks and do seo to get targeted organic traffic. If at all you are very particular to drive traffic to your new site, you can think of google adwords
some of you are wrong ... if you use ppc programs you will not get unique visitors! just a a lot of visits from the same few list of ip's. if you bought traffic from someone and you received it in a few days, than YES you are right, don't buy traffic, because you probably received it in the same way as ppc (no unique ip's, or if are unique they could be computer generated or fake). But there are some the sell traffic from unique visitors (like http://traffic.wtools.eu) and that's what counts for serach engines! And people, the point of buying traffic is not that you will sell through that traffic, but you will be in the front pages of a search engine and that's what really matter. You should buy a small package and see for yourself how it's works and if it's bad traffic.
