Best you can do for now is do some SEO for your site and focus more on link building. The most common ways of getting backlinks are thru social bookmarking, directory submissions, submitting to press release sites, forum sigs, etc. etc.. What's important from an SEO point of view is getting relevant (same niche) and quality (organic / natural) back links. Also having back links to high PR sites helps your site on PR building as well.
On a marketing perspective IMO, having more targetted link backs is very important as these yields the highest conversion rate. In general, the more link backs you have - the more exposure your site gets - the more chances you get traffic from these back links. Best of luck
