[Jakester]

Sounds like you have been ctively employing seo techniques, it can take month for your site to be 'credited' with some backlinks, you may continue to develop more orgainic traffic as time goes by.

The big time seo professionals have additional assets that enable them to quickly generate traffic, chiefly networks of sites with good search engine ranking on which they can add links to your site. Some seo companies also run free link exchange pools, that they can tap into as an additional source of links.

If you have identified the value of a visitor, you can budget a larger paid advertising campaign using other channels. Adwords is one of the more expensive methods, though it's useful for measuring the effectiveness of an ad at a low volume. To advertise more broadly, you may want to go to media buys, the sort of network advertisement some spend thousands a day on. Generally banners or pop-up pages using cpm pricing, several of the big names have minimum prices of $100 to $200. A secondary benefit of displaying a banner thousands or millions of times is brand awareness, some studies show that a familiarity with a brand through repeated exposure, even at a subliminal level helps establish the trust level needed to convert to a paying customer.
A couple of the big paid media suppliers are:

Advertise.com text and display ads, $100 min. good quality traffic
Clicksor.com cpc ads delivered in a variety of methods. $100 min.
AMPKeywords.com a smaller cpc text ad network, $100 min.

AdBrite.com text and display ads, $100 min. cheap ads, lower quality network, tolerating more diverse advertisers, cpc may be a safer bet with them, watch where your ads are placed.
