We've got one here in Canada called Bridal Services Network that I have been using - it costs $0.75 for new leads, and as the lead gets older, the cost goes down until it is free. You can also pay a "premium service" to get your name up top and highlighted - this costs $0.10 per click (or free for those brides who multiple click you!) every time a bride links to your website. I have been getting great feedback from the "pay-per-click" service, not so much with the "pay-per-lead" (although I have been picky about who I contact!).
For those Canucks who are interested, the website is https://www.bridalnetwork.net/
