Rambler uses begun.ru for their ad serving. You can visit the latter website and find a little link at the bottom of the page that would take you to an English description of the company.
One more place that you might want to look at for Russian PPC traffic is yandex.ru - there is a small link at the bottom of the site with an info in English for advertisers.
I hope this helps..
