You can try PPC for your business as part of your marketing strategy. Additionally, start doing SEO on your site for maximum visibility. You can also try sending newsletters in case you have a list of followers.
I would try social bookmarking and networking online as a start. Twitter is really good in the area of getting some quick traffic to your website or blog.
