Generate Website Traffic / New Leads for our Website

I have a Fashion only classifieds site and want more listings. The site is free to use so this job is easy! I need someone to contact people that are already selling items through Gumtree/Kiji/CL and similar classified sites and alert them to the fact that they can also post their items for sale on my site as well free of charge. This is not about stealing clients from other classified sites, this is about informing people that are already selling such items that there is a another free option for them to try. My site operates worldwide in primarily English speaking countries so there is a lot of people you can contract to get the job done. I would like 500 new listings, 100% all real, no fakes, I will give you a short-link to track your signups. I will give you the sites I think you should contact through and also some basic scripts you can email. pretty much all you need to do is find someone selling a product on a classifieds site that could be sold on mine and send them the script through the built in contact form where they are currently selling. I will provide the script and details of the target group once I award the project, but in general it is women's fashion, clothing, shoes & accessories.
