Use this Siteometrics tool to search, by keyword or key phrase, for sites that may offer to provide a link to your site. The tool is based on a multiple keyword search and may provide sites that offer to sell links, submit sites for a fee or discuss site linking. The tool is not perfect but you may find a useful site that will provide a link to your site. The returned links show the PageRank and are clickable, allowing you the option to connect to the site.
