russian search engine promotion

I have a real estate website that is translated in to Russian with a .ru domain name. I am looking to promote this site on the main Russian language search engines including Yandex, Rambler and [login to view URL] The site has good coverage on standard Google with its .com domain The business is real estate in the South of France and I notice there is not too much competition so this should be quite straight forward. If all goes well I would be happy to pay a monthly fee in the future to maintain performance. Only geniune professionals with proven track record need apply and I would prefer to work with a Russian company to ensure the best possible service.
